Industrial robot bearings are the unsung heroes inside your machines. Just like human joints, they need regular care to ensure smooth movement, precision, and long service life.

To keep your robots performing at their best, follow this simple 3-step maintenance routine:

The Essential Three-Step Bearing Care Routine

1. Deep Cleaning is Key

• Use a cleaning solvent such as a specialized degreaser or kerosene (avoid harsh chemicals).
• Remove all old grease, dirt, and metal particles.
• If there’s rust, gently sand it off with fine-grit sandpaper until the surface is smooth.
• Rinse thoroughly after cleaning.

2. Fight Rust Effectively

• Dry the cleaned bearings completely using a clean, lint-free cloth.
• Soak them in high-quality rust-preventive oil.
• Rotate the bearing while submerged to ensure full coverage — this creates a protective film that prevents corrosion.

3. Proper Lubrication is Vital

• Apply the correct lubricant (grease or oil) as specified by your robot manufacturer.
• Spread it evenly over the entire bearing — including inner and outer rings, balls/rollers, and the cage.
• Rotate the bearing while applying to help the lubricant reach all internal parts and reduce friction.

Beyond the Basics: Supporting Best Practices

For optimal performance, go beyond basic maintenance with these additional steps:

• Follow the Rules

Train operators to use and maintain the robot correctly. Proper operation reduces stress on bearings.

• Keep it Clean

Maintain a clean workspace. Dust and debris can enter bearings and cause damage over time.

• Check Regularly

Listen for unusual noises, feel for vibrations, and monitor temperature changes — these are early signs of bearing issues.

• Replace Wisely

Don’t wait for failure. Replace worn bearings and related parts (like seals or gears) proactively. Always use genuine replacement parts.

• Stick to the Schedule

Create and follow a maintenance plan based on usage and environment (e.g., more frequent lubrication in dusty or hot conditions).

Why This Matters

Good bearing maintenance isn’t just routine work — it’s an investment in your robot’s performance and longevity. Benefits include:

• Maintained precision and accuracy
• Extended service life of components
• Reduced downtime and production loss
• Consistent smooth and efficient operation
