Hello, about the bearing problem. Sliding bearings are made of powder metallurgy. What kind of grease does it use?

Answer:

You say is the ultra high temperature lubricating powder, and thread anti card grease, the grease types include the following:The total synthesis of anti - thread copper card containing metal powder, grease, commonly known as golden oil, thread, assembly and seal for high temperature.The total synthesis of high temperature anti - white fat card, the connotation of non metal powder. Mainly used for high temperature lubrication, demoulding, assembly, sealing.Total synthesis - black thread sealing grease containing MoS2 powder for bolt thread, casing, drill pipe etc..At present, the product, the tiger head, hotolube and Kluber series of more complete, stable quality. The metallurgical powder you are talking about may be the first or the third. Please choose according to the use.
Powder metallurgy bearing is lubricated bearings in the factory will be through the vacuum method of negative pressure adsorption added lubricating oil, in the late stage of the process slowly release and consumption, good quality of powder metallurgy bearing life can reach more than ten years.This type of bearing is recommended to not add lubricating oil or grease, add after will have to change the bearings of the environment, such as dust adhesion, friction coefficient change, oil smoothly, when oil was crushed, and the lubrication performance of powder metallurgy bearing itself and do not come out to play, will become very astringent a card, caused by poor lubrication, which often needs to be added, resulting in unnecessary consumption and fee of manpower. Of course, there is a powder metallurgy sliding bearing is not oily, there is grease, add glib, this is often need to add fat.
