What Is Powder Metallurgical Bearing?
Jiashan Dernore Bearing Co.,Ltd | Updated: Jul 31, 2018

Powder metallurgy bearing can not be added lubricating oil for a long time.


The higher the pore rate of powder metallurgy bearing, the more oil storage, but the more diesel engine copper sleeve of the pore , the lower the strength.


This type of bearing is usually in mixed lubrication, and sometimes the powder metallurgy bearing can form thin film lubrication, which is often used to supplement the difficulty of lubricating oil and light load and low speed.


According to different working conditions, powder metallurgical bearings with different oil content are selected. When the oil content is high, it can be used in JTW self-lubricating washers without adding lubricating oil and low load. Oil bearing rate can be applied at heavy load and high speed. Graphite - bearing powder metallurgy bearing, because graphite itself is lubricity, can improve the safety of bearing, its drawback is strength is low; In the absence of corrosion, it can be considered that the iron base powder metallurgy bearing with low price and high strength can be considered, but the axial rigidity of the matched shaft should be improved appropriately.
