Overview of Self-Lubricating Bearings
SF-1 universal steel base without oil self-lubricating bearings:
1.Oilless or less oil lubrication, can be used without maintenance or less maintenance.
2.Wear resistance is good, the friction coefficient is small, long service life.
3.Has the right amount of elastic-plastic, can stress distribution in a wide contact
surface, improve the bearing capacity.
4.Static friction coefficient is similar, so as to ensure the accuracy of mechanical work.
5.Can make machinery to reduce vibration, reduce noise, prevent pollution, improving
6.In the course of the operation can form a transfer film, play a role in the protection
of the grinding shaft.
7.For the gringding shaft hardness requirements are low, thereby reducing the processing
of the relevant parts of the difficulty.
8.Thin-walled structure. light weight, can reduce the mechanical volume.
9.Steel back can be plated with a variety of metals, can be used in corrosive media, has
been widely used in a variety of mechanical sliding parts.
Self-lubrication bearings are made of composite self-lubricating bearings, solid inlaid
self-lubricating bearings, bimetallic self-lubrication bearings, special materials, self-
lubricating bearings, according to different users and conditions, use different self-lubricating
One of the major categories of solid inlaid self-lubricating bearings (referred to as JDB
) is a combination of metal bearing characteristics and non-oil lubricated bearing
characteristics of the new lubricating bearings, from the metal matrix to withstand the load, the
special formula of solid lubricating material lubrication.
It has the characteristics of high carrying capacity, impact resistance, high temperature
resistance and high self-lubricating ability. It is especially suitable for occasions such as
heavy load, low speed, reciprocating or swinging and so difficult to lubricate and form oil film,
and is not afraid of water erosion and other acid and souring. Products have been widely used in
metallurgical caster, rolling equipment, mining machinery, mold, lifting machinery, taxtile
machinery, wind power generarion, ships, steam turbines, turbines, injection molding machines
and equipment production lines. Wear resistance is twice that of ordinary bushings.
