Solid-lubricating Bearings

Profile

Self-lubricating bearings ate used where the beadng is working without lubricant or with marginal lubricant during operation Our focus is on ensunng that the bearing gives the best performance and the longest life under vanous conditions The working principle of self-lubricating bearings is that dunng the initial run-in period of the bearing, there will be a solid lubricating film created by the transference of a small amount of material from the bearing layer which is in direct contact between the moving parts and this layer will protect and lubricate the mating components, thus extending the service life of the bearing and shaft.

Feature

Modern designs place enormous demands on today's self- lubricating beanng materials.requires free maintenance operating even under severe environment and extremely load conditions Moreover, the constant pressure on costs request for increasing machine and plant availability without any loss of reliability. The metallic self-lubricating bearing materials developed by SLT carl meet the maintenance-free as well as self-lubncated at long-term operating,which makes the design of reliable long-term self-lubricating system possible SLT metallic self-lubdcating bearing materials can be applied to a wide range of low-speed high-load conditions like the rotating, swing and straight-line reciprocating motion: Meanwhile, this kind bearing materials are suitable for the tradition lubdcation cannot given or prohibited occasion, or in special conditions such as dust, radiation, impact Ioad but required the use of long-term and stability.

  • Application
a

JDB materials consist of highly wear-resistance copper cast alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work condition, high-strength copper alloy provides a high load-bearing capacity and the solid lubhcant can be formation of low friction nIm Under technical dry running conditions. The bearing surface is designed with thick running-in film which enables the solid lubricant to be transfened to the counter materiaI at the first contact.
