Thrust Bearing and Its Components
SLZ---thrust bearing and its components is a unit composed of thrust
cage and needle roller or cylindrical roller, or thrust ball with thrust
washer. It can also consist work-pieces used separately. Featuring compact
structures, capability of bearing single-direction axial force, high
loading ability and high rigidity. It is widely used in lathe,
metallurgical and textile machinery; motor, driving shaft, gearbox and
other location & supporting location.
For bearing rolling body, various structures of thrust
balls, needle rollers and cylindrical rollers are available.
cages, materials of steel and non-ferrous metal can be chosen.
are different structures of cages, such as machined &
