Correct lubrication separates rolling elements from raceways, carries heat away and protects against corrosion. Too little or too much lubricant can both shorten bearing life.
Quantity and interval depend on bearing size, speed, temperature, load and environmental cleanliness. A grease-filled housing needs free space for movement and heat dissipation.
What to Focus On
- base-oil type and viscosity
- operating temperature and speed
- compatibility of old and new grease
- cleanliness of lubrication tools
- temperature check after relubrication
Recommended Procedure
- Confirm the recommended lubricant and dose.
- Clean the grease fitting and surrounding area.
- Add grease in controlled small quantities under suitable conditions.
- Monitor temperature and the path for excess grease.
Common Mistake
Packing the housing completely with grease often increases drag, temperature and energy use.
Summary
Good lubrication is a controlled process built on the right quantity, cleanliness and follow-up checks.
