| Function of bearing lubrication | ||||||||||||||||||||||||||||
| Lubrication has important effects on the lifetime, friction, abrasion and temperature rise of a roller bearing. Bearings will not be able to perform their normal functions without proper lubrication. Most bearing failures are related to poor lubrication. Therefore, good bearing lubrication is an effective measure for reducing friction and wear. Furthermore, good lubrication has heat dissipation, rust proof and shock alleviation functions. | ||||||||||||||||||||||||||||
| Grease | ||||||||||||||||||||||||||||
| Grease is a kind of lubricant made of mixing base oil thickener and additives. The appropriate grease should be chosen to meet the environmental conditions of the bearing since different greases can make a big difference in performance. Commonly used greases include calcium-based grease, sodium-based grease, lithium-based grease and molybdenum disulfide grease. Ideally, grease should be filled to 1/2 to 1/3 of the bearing space; it should be reduced to 1/3 for high speed because excess grease will cause resistance and the temperature to rise. | ||||||||||||||||||||||||||||
| Lubricating oil | ||||||||||||||||||||||||||||
| In high–temperature conditions, lubricating oil can be used instead of grease because a cooling effect can be achieved by circulating the lubricating oil, thus extending the bearing service life. | ||||||||||||||||||||||||||||
