Advantages Of grease Lubrication And Oil Lubrication In Rolling FAG Bearings

Advantages of rolling FAG bearings lubricated with oil:
1) Under certain operating specifications, the starting torque and friction loss of lubricating oil are significantly smaller than that of grease lubrication.
2) Since the lubricating oil takes away heat during circulation and plays a cooling role, it can enable the FAG bearing to reach a relatively high rotation speed.
3) It can ensure reaching a relatively high operating temperature.
4) When changing grease, the relevant connecting parts must be disassembled. When lubricated with oil, there is no such trouble.
5) It is very suitable to lubricate the FAG bearings in the reduction box with lubricating oil, because the oil achieves the purpose of lubrication of the gears and FAG bearings at the same time by splashing. 6) The grease in the FAG bearing is gradually contaminated by products of product wear, abrasives, products that penetrate through the sealing device from the outside and age themselves. If not replaced in time, it will cause accelerated wear of the FAG bearing, and when using liquid lubricants , can be filtered to ensure its normal operation.

Advantages of grease lubrication for rolling FAG bearings:
1) Some FAG bearing points must be refueled frequently by hand. If you use grease, it will save trouble and avoid accidents caused by lack of oil.
2) The grease itself has a sealing effect, which allows the use of a mechanism with a low degree of sealing to simplify the design.
3) Experience has proven that within a certain speed range (n<20000r/min or dn<20000mm.r/min), lubrication with lithium-based grease has a lower temperature rise and longer FAG bearing life than the oil dripping method.
