Lubricating oil for bearings is a crucial factor in ensuring smooth bearing operation, maintaining bearing performance, and extending the service life of bearings. The role of lubrication is particularly important for cross roller bearings. Below, the Ovite editor will provide you with a detailed introduction to the functions of lubrication for cross roller bearings, as well as guidance on how to select the appropriate lubricant and methods for doing so.
I. The Role of Lubrication in Crossed Roller Bearings
1. The role of lubrication
(1) Lubricate all parts of the bearing to reduce rotary friction between the raceway surfaces and steel balls, sliding friction between the steel balls and the retainer, and sliding friction between the retainer and the guiding surfaces of the raceways.
(2) Remove the heat generated by internal friction within the bearing as well as other heat transferred from external sources. This prevents the bearing from overheating and the lubricant from degrading.
(3) Ensure that the rolling contact surfaces of the bearing are regularly coated with an appropriate oil film. This helps to relieve concentrated stress caused by impact loads and extend the bearing’s fatigue life.
(4) Prevent rusting of the steel balls, raceways, and retainers, as well as the intrusion of debris, foreign objects, and moisture.
2. Functions of lubricating oil
(1) Lubrication: Provides a lubricating oil film that separates friction surfaces. Cold-start wear accounts for 70% of the engine’s total wear.
(2) Cleaning: Contaminants are washed away from the lubricated parts of the bearing and dispersed into extremely fine particles for removal.
(3) Cooling: Reduce the heat generated by friction and dissipate the heat away through circulation to achieve cooling.
(4) Corrosion prevention: Prevents corrosion of components caused by air and water.
