Proper lubrication for rolling bearings is essential for reliable operation. Given that some leading bearing companies have stated that incorrect lubrication can account for more than 30 percent of bearing failures, lubrication is a key influence that can make or break bearing service and life.

The lubricant provides a separating film between the bearing rolling elements, raceways and cages to prevent metal-to-metal contact. By controlling surface contact, the lubricant is able to minimize the effect of surface contact, namely undesired friction that otherwise would generate excessive heat, metal fatigue and wear. The lubricant must also prevent corrosion and contamination damage.

Grease has become a common lubricant choice for rolling element bearings. The practical benefits are apparent: grease is easy to apply, can be retained within a bearing’s housing and offers protective sealing capabilities.
