Metal-polymer self-lubricating bearings

Short Description:

The metal polymer self-lubricating bearing mainly bears radial load, and can also bear radial load and axial load at the same time. Its structure is simple, and compared with other types, it is easy to achieve higher manufacturing precision, so it is convenient for mass production, and the manufacturing cost is also low. Low, use the most common. Metal polymer self-lubricating bearing is the most representative rolling bearing, with small friction coefficient, high limit speed, simple structure, low manufacturing cost, easy to achieve high manufacturing precision, mainly bearing radial load, and can also bear a certain amount of axial load . Axial load capacity increases when larger radial clearance is selected.

Specifications

Structure
1). PTFE/Fibre mixture thickness 0.01~0.03mm, provides an excellent initial transferred film, which effectively coats the mating surfaces of the bearing assembly to establish the self-lubricating feature.
2). Sintered bronze powder thickness 0.20-0.35mm, provides strong mechanical bond and excellent thermal conductivity.
3). Steel backing Provides mechanical strength.
