  Simple Lubrication & Dust Protection Tips Ball screw support bearings are key to smooth, precise machine movement. But if you don’t take care of them — especially with lubrication and dust protection — you’ll face breakdowns, downtime, and poor performance. Here’s how to keep your bearings working well for longer. Why Lubrication Matters Good lubrication is not optional. It: Reduces friction – Stops metal parts from rubbing together. Cools the bearing – Helps avoid overheating. Prevents rust – Protects against moisture and corrosion. Keeps motion accurate – Ensures smooth, stable operation. Choose the Right Lubricant For Most Machines (Low to Medium Speed) Use grease — it’s simple and effective. Lithium-based grease (NLGI 2) – Good for general use. Synthetic grease (Polyurea or Aluminum Complex) – Lasts longer, handles higher speeds. High-temp grease (Bentonite or Silicone-based) – For machines over 120°C. Heavy-duty grease (EP or MoS₂ additives) – For high-load applications. Tip: Fill only 1/3 to 1/2 of the bearing space. Too much grease = too much heat. For High-Speed Machines (>3000 RPM) Use oil instead of grease for better cooling. Low-viscosity synthetic oils (ISO VG 32 or 46) Oil mist or air-oil systems – Great for clean, fast operations. How Often to Lubricate? It depends on speed and environment. Use this as a guide: Bearing Speed Manual Lubrication Automatic Lubrication Low (3000 RPM) Every 50–100 hrs Every 10–30 hrs Watch for Warning Signs Too hot? If the bearing feels more than 15°C warmer than room temperature, check the lube. Noise? Grinding or scraping sounds usually mean poor lubrication or dirt inside. Leaks? Grease coming out = too much grease. Don’t Forget: Dust is Dangerous Dust and debris act like sandpaper inside bearings — they wear parts down fast and cause noise and failure. Best Ways to Block Dust Seals – First Defense Rubber Lip Seals: Good for slower machines (

  If your gearbox is making strange noises — like a whine, grind, or knock — it’s time to pay attention. These sounds are often early signs of bearing problems that, if ignored, can lead to serious breakdowns, costly downtime, and expensive repairs. In this article, we’ll walk you through the most common causes of noisy bearings and what you can do to fix them — before things get worse. What Causes Noisy Gearbox Bearings? Here are the most common reasons why bearings start making noise: 1. Poor Lubrication This is the number one cause of bearing noise. Not enough grease or oil? Friction goes up, parts overheat, and you hear grinding or high-pitched noise. Wrong type of lubricant? If the viscosity is off or it doesn’t handle the temperature, the oil or grease won’t protect the parts well. Dirty lubricant? Dust, metal bits, or water in the oil/grease will wear down the surfaces and make rough, rumbling sounds. 2. Worn or Damaged Bearings Bearings don’t last forever, especially if they’ve been under heavy load or high speed for too long. Pitting or flaking on the surface leads to rhythmic knocking or crunching. Cracks, dents, or broken parts from impact or overload cause irregular noises — like clunking or scraping. 3. Contamination Dust, dirt, or process debris getting inside the bearing housing will scratch and wear down the parts. You might hear a gritty or rough sound when the machine runs. 4. Installation Mistakes Even small mistakes during installation can lead to big problems. Misalignment creates uneven pressure and causes humming or howling sounds. Too loose or too tight fits lead to vibration (roaring) or heat and noise (whining). Hammering bearings into place damages rolling elements or raceways — and makes noise right away. 5. Overloading or Harsh Conditions Pushing the gearbox beyond its limits — whether by speed, load, or environment — can quickly damage bearings. Too much load changes the shape of parts and causes loud knocks. Too much speed without proper cooling = screeching. Sudden shocks can break parts instantly. How to Fix It: Practical Solutions 1. Get Lubrication Right Use the correct oil or grease as recommended by the manufacturer. Keep the oil level right and change it regularly based on use and conditions. Always keep everything clean when adding or replacing grease — no dirt or dust allowed. 2. Watch Bearings Closely Check for noise, heat, and vibration regularly. Replace damaged bearings right away — don’t wait. Make sure seals are working so dirt stays out and grease stays in. 3. Install with Care Use the right tools — no hammers! Line up shafts and housings precisely, usually within 0.05mm. Double-check fit between shaft/housing and bearing — it matters! 4. Run Machines Smartly Stay within load and speed limits. Protect gearboxes from dust, moisture, and extreme temperatures where possible. 5. Build a Simple Maintenance Plan Set regular times to lubricate, inspect, and test. Train your team to spot early warning signs. Only use quality parts from trusted suppliers. Final Thoughts Noisy bearings aren’t normal — they’re warnings. Don’t ignore them. With better lubrication, careful installation, and regular checks, you can stop small issues from turning into big failures. Keep your machines running longer and smoother by staying ahead of bearing problems. Need Help? If your gearbox is making noise and you’re not sure why, feel free to reach out.

  Standard contact angles for angular contact ball bearings typically include: C – 15° AC – 25° B – 40° TAC / 760 Series – 60° These are commonly used in precision spindle applications. In addition, there are also non-standard contact angles, such as 18° and 21°, which may be used for specialized performance requirements or customized designs.

  You receive a new spindle bearing — it looks clean, maybe even greased. So, is it ready to install? Not necessarily. Many machine builders and maintenance engineers assume that the protective coating on new bearings is also functional lubrication. But in reality, this isn’t always the case. Improper handling of new spindle bearings can lead to: Reduced performance Increased noise and vibration Premature failure This guide will help you make the right decision — whether to clean or not to clean — based on real-world experience and industry best practices. Sealed vs. Open Bearings — Know What You're Dealing With Do NOT Clean: Sealed or shielded bearings, which are often pre-lubricated with grease designed for both protection and operation. These bearings are shipped ready to install. Cleaning them risks removing essential lubricant or damaging the seals. Must Clean: Open bearings coated only in rust-preventive oil. Important: This type of oil is not a lubricant. It’s applied during storage and shipping to prevent corrosion. Leaving it in place can: Contaminate your spindle's lubrication system Reduce bearing performance Shorten service life So yes — if you’re working with open bearings, cleaning before installation is strongly recommended.  When Cleaning Is Even More Critical Even sealed bearings may require cleaning under certain conditions: 1. Visible Contamination If the bearing arrives with: Dust Metal particles Moisture or signs of corrosion Cleaning (or replacement) is necessary. 2. High-Speed or Precision Applications In high-performance machining centers or ultra-precision equipment, residual factory oils — even from “clean” bearings — can affect performance. Some shops choose to clean as an extra precaution. 3. Lubricant Incompatibility If your spindle uses a specific grease different from any pre-applied lubricant (except dedicated dual-purpose grease), thorough cleaning is required to avoid mixing incompatible greases.  How to Clean Spindle Bearings Properly (If Needed) When cleaning is necessary, follow these steps carefully to avoid damage: Step 1: Initial Degreasing Use a low-VOC solvent like kerosene. Submerge the bearing. Gently brush off heavy dirt or grease without rotating the bearing — spinning it now could scratch the raceways. Step 2: Final Rinse Transfer the bearing to a fresh container of clean solvent. Now gently rotate it by hand while submerged to flush out fine particles. Step 3: Dry Thoroughly Wipe dry with a lint-free cloth — medical-grade cotton works well. Or use filtered compressed air to blow off remaining solvent. Don’t leave the cleaned bearing exposed — proceed to lubrication quickly. Step 4: Apply the Right Grease Use the manufacturer-recommended spindle grease. Never mix greases unless you know they are compatible. Step 5: Final Check Rotate the bearing by hand — movement should be smooth and quiet. If there's roughness, noise, or play, stop and investigate — something may be wrong. Final Thoughts: Small Steps, Big Impact Cleaning new spindle bearings might seem like a minor step — but it plays a major role in ensuring long-term performance and reliability. Sealed bearings with dual-purpose grease? Install directly. Open bearings with rust-preventive oil? Clean before use. High-speed or precision applications? Extra care pays off. Lubricant mismatch? Can cause serious issues down the line. By taking a few minutes to ensure proper cleaning and lubrication, you’re setting up your machine for smoother operation, less downtime, and longer life.  Need Technical Support?

Spindles are critical components in many machines, and when they start making noise, it can be concerning. However, not all noise comes from worn bearings — there are several possible causes. Understanding what's really behind the sound helps you make better decisions and avoid unnecessary repairs or replacements. Common Causes of Spindle Noise 1. “I’m Just Thirsty!” – Lubrication Problems Lack of lubrication or old/degraded grease/oil is the most common cause of noise. Bearings need clean, correct lubricant to run smoothly. Low or dirty lubricant → increased friction and heat → rough or dry sounds Wrong type of grease for your spindle speed/temperature can also cause issues 2. “I’m Stressed!” – Installation or Alignment Issues Improper installation or misalignment puts stress on bearings: Uneven fit or damage during installation Shaft misaligned by more than 0.02 mm This leads to uneven wear, vibration, and abnormal noise. 3. “Something Else is Loose!” – Mechanical Looseness Loose parts like pulleys, couplings, or mounting bolts can rattle or vibrate. Sometimes internal motor components may also shift slightly and create noise that sounds like bearing failure. 4. “My Power’s Wonky!” – Electrical Problems Electrical issues can cause unusual sounds that have nothing to do with bearings: Unstable voltage Faulty windings Incorrect VFD (Variable Frequency Drive) settings These often cause a high-pitched hum or whine. 5. “I’m Overheating!” – Cooling Problems Poor cooling leads to overheating, which causes bearings to expand and rub harder: Blocked airflow Failed coolant pump Clogged cooling passages Even the fan itself can become noisy if clogged or damaged. 6. “Okay, Maybe It Is Me…” – Bearing Wear or Failure Sometimes, it really is the bearings: Bearings near or past their life span (~2000 hours for high-speed spindles) Physical damage from shock or contamination Signs: loud grinding, pitting, discoloration, strong vibration, or heat What to Do When You Hear Noise Don’t rush to replace bearings — first, check these:  Listen & Feel What kind of noise? (Whine, grind, rumble?) Is there vibration when touching the housing? Is the spindle unusually hot? Check the Basics Lubrication: Is it clean and at the right level? Try re-lubricating with the correct type. Cooling: Make sure air or coolant flow is unblocked. Tightness: Check for loose bolts, pulleys, or couplings. Electrical System: Confirm stable power supply and correct VFD settings. Evaluate Usage How many hours has the spindle been used? Near 2000? Bearings may be due. Has it been overloaded or hit hard? Could resonance at certain speeds be causing the noise? Try adjusting RPM slightly. When to Replace Bearings Replace bearings if you notice: Severe or increasing vibration Localized heat rise over 40°C Visible damage (cracks, pitting, discoloration) Reaching service life with ongoing noise Loud metallic grinding or scraping sounds Why Quality Bearings Matter Using high-quality bearings like those from Beining Technology makes a real difference: Precision manufacturing reduces vibration Optimal design for high-speed applications Superior materials and lubricants reduce friction and noise Rigorous testing ensures long life and quiet operation Custom solutions matched to your specific use case prevent misapplication Final Thoughts Noise doesn't always mean bad bearings. Often, the problem is something simple like lack of lubrication, loose parts, or electrical issues. Diagnosing the real cause saves time, money, and downtime. But when it’s time to replace bearings, choosing precision-engineered options from trusted suppliers like Beining Technology ensures smooth, quiet, and long-lasting spindle performance. Need Help?

Oil leakage from small electric motor bearings is a common issue that can lead to equipment downtime and reduced performance. While leaks are frequent, they usually result from identifiable causes — and with the right approach, they can be effectively managed or even prevented. By understanding the root causes and applying practical solutions, maintenance teams can significantly improve motor reliability and extend service life. Common Causes of Bearing Oil Leaks 1. Seal Failure Seals are the first line of defense against oil leakage. Issues include: Worn or damaged seals due to heat, age, or friction. Improper installation, such as misalignment or insufficient compression. Material incompatibility with temperature, speed, or lubricant type. Gaps between shaft and housing caused by wear. 2. Lubrication Problems Lubricant-related issues are a major cause of leaks: Overfilling increases pressure and forces oil past seals. Wrong lubricant for the environment or application leads to breakdown. Degraded oil/grease loses its properties and may foam. Poor oil circulation due to incorrect pressure, clogged filters, or improperly sloped return lines. 3. Mechanical Wear and Misalignment Physical wear and improper alignment can also cause leaks: Worn bearings or shafts allow unwanted movement that damages seals. Misaligned shafts cause uneven seal wear and early failure. 4. Environmental and Pressure Factors External conditions contribute to oil leakage: Pressure imbalance from blocked or poorly placed vents pushes oil out. Dust, moisture, or corrosive environments damage seals and degrade lubricants.  Practical Solutions to Prevent Oil Leaks 1. Seal Improvements Use high-quality seals like Fluorocarbon Rubber (FKM) for better durability. Install seals correctly using proper tools and techniques. Ensure smooth shaft surface (Ra ≤ 1.6 µm) and avoid twisting during installation. 2. Proper Lubrication Management Fill grease to about 50–60% of the bearing space. For oil systems, keep levels between 1/3 and 1/2 of the sight glass. Choose the right lubricant based on operating conditions (temperature, speed). Maintain oil systems: clean filters, control pressure (0.1–0.8 MPa), and ensure proper return line slope (≥15°). 3. Address Mechanical Issues Align shafts precisely (within 0.02 mm tolerance). Replace worn bearings or shafts promptly to avoid further damage. 4. Control Environment and Pressure Keep vents clean and install filters where dust is an issue. Place motors in dry, clean areas when possible. Clean motors regularly to prevent dirt buildup. 6. Proactive Maintenance Helps Prevent Future Leaks Schedule regular inspections of seals, lubricant levels, and motor condition. Monitor bearing temperature and vibration to catch problems early. Use quality parts from trusted suppliers to avoid repeated failures. Follow manufacturer guidelines for installation and maintenance. Keep detailed records of all service work for future reference. When to Act Immediately If you notice any of these signs, shut down the motor right away: Strange noises (grinding, screeching) Sudden temperature increase These could signal imminent bearing failure, which may cause serious damage if ignored.  Conclusion Oil leakage in small electric motor bearings is not inevitable. With proper sealing, correct lubrication, precision alignment, and routine maintenance, most leaks can be avoided. By taking a proactive approach, companies can reduce downtime, improve efficiency, and get more value from their motor systems.
