What are the advantages of using grease on bearing？

Grease used on bearings is very important. Its application is very wide, as long as there is movement, basically need to use lubricating grease, today xiaobian to say what are the benefits of using grease on bearings:

First, the adhesion is good, the ability to maintain on the friction surface is strong, and the sealing is good, so the grease can work on the open and poorly sealed friction parts. It can prevent the invasion of moisture and dust and protect the metal from long-term corrosion. The device can be turned upside down without producing oil leaks. Shutdown for a period of time, can operate as usual, and do not need special maintenance. Can avoid oil leakage, dripping oil caused by mechanical pollution.

Second, the use of grease on bearings can greatly simplify the outer dimension of bearings, without the need for complex sealing devices and oil supply system, which is conducive to the miniaturization and lightweight of equipment.

Bearing oil third, oil film thickness, grease on low speed bearing high load and impact load parts, have good lubricity. The damping effect of grease is good, and the noise of bearings is relatively low.

Fourth, long service life, less oil supply, do not need to often add, in the friction parts that are difficult to often add oil, the use of grease is more favorable. There are some sealed bearings, you can fill grease in the bearing factory, has been used until the end of the bearing life, there is no need to replace or add grease.

Fifth, the use of a wide range of grease can be lower than the base oil freezing point of 10℃ under the condition of starting. This is because after short-term operation of grease in bearings, the distribution of grease is a thin layer of oil film, friction point is some point or line contact, than full immersion oil bath lubrication bearing resistance is small, it is easy to start.

See here hope readers can correctly use grease, can increase the service life of bearings, reduce noise, reduce friction and so on.
