Economical bearing: insert type solid lubrication bearing

Inlaid bearings not only save oil and energy, but also have longer working life than ordinary sliding bearings.Metal base inlaid solid self-lubricating bearing  is a kind of novel self-lubricating bearing which has the characteristics of both metal bearing and self-lubricating bearing.The metal substrates bear most of the load during the friction process.Through friction, the solid lubricant in the oilless bearing bushing in the hole or groove transfers or reversely transfers to the friction surface, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, which greatly reduces friction and wear.As the friction of self-lubricating steel sleeve is carried out, the embedded solid lubricant is constantly provided on the friction surface to ensure good lubrication of the friction pair during long-term operation.It breaks through the boundaries of ordinary bearings depending on oil film lubrication.It has the advantages of high bearing capacity, impact resistance, high temperature resistance, small friction coefficient, low abrasion, no noise, strong self-lubrication performance, etc.It is especially suitable for heavy load, low speed, reciprocating or oscillating, etc.
