Latest company news about Why Your Electric Motor Bearings Keep Failing (And How to Fix It)

At Beining Intelligent Technology (Zhejiang) Co., Ltd., we understand the critical role electric motors play in industries ranging from manufacturing to home appliances. Did you know that 80% of motor bearing failures are due to common, preventable mistakes? Our expertise has helped thousands of customers avoid these costly issues. Here’s how to identify and prevent common bearing failures.

 


1. Dry Bearings: The Silent Destroyer

Problem: Insufficient lubrication leads to metal-on-metal contact, generating tiny metal shavings.

  • Signs: Grinding noises or unusually warm bearings.

  • Solution: Conduct regular monthly lubrication checks, use high-quality lubricants suited for your operating temperature, and avoid over-greasing to prevent excessive heat buildup.

2. Dirty Bearings: Mud & Sand Are Your Enemies

Problem: Contaminants like dirt and sand scratch bearing surfaces, causing premature wear; water mixed with grease forms corrosive sludge.

  • Solution: Install protective shields in dusty environments, choose sealed bearings for outdoor applications, and regularly clean equipment using clean gloves.

3. Misaligned Motors: When Your Machine Starts Shaking

Problem: Even a slight 0.1mm misalignment can triple bearing stress, leading to vibrations that cause metal fatigue.

  • Solution: Utilize laser alignment tools for precise adjustments, ensure bolts are tightened evenly in star patterns, and check for uneven floors or supports.

4. Electrical Strikes: Surprises from Your Wiring

Problem: Voltage spikes create tiny pits on bearing surfaces, breaking down lubricant and accelerating wear.

  • Solution: Work with electricians to inspect wiring for voltage issues, consider insulation coatings for high-risk applications, and install grounding systems for motors.

5. Overloading: Pushing Bearings Too Hard

Problem: Overloaded bearings flatten prematurely, leading to early failure and excessive heat that melts the lubricant.

  • Solution: Consult load specifications when selecting bearings, use vibration sensors to detect abnormal operation, and upgrade to heavy-duty bearings as needed.
