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.
Types of
Designs:
For bearing rolling body, various structures of thrust
balls, needle rollers and cylindrical rollers are available.
For
cages, materials of steel and non-ferrous metal can be chosen.
There
are different structures of cages, such as machined &
punched.
Product Precision Accuracy:
Dimensional
tolerance and geometrical accuracy is based on GB/T307.
Matched
cylindrical roller precision grade is Ⅲ (ISO GB/T4661).
Mutual
difference of needle roller diameter is 2μm, and the precision grade is G2
(ISO GB309).
Matched steel ball accuracy is grade 20 (ISO
GB/T308).
Materials:
Material for rolling body is GCr15
bearing steel, quench-hardening HRC60---65.
Material for thrust washer
is GCr15 bearing steel, quench-hardening HRC61---65.
Material for
punched parts is quality low-carbon steel.
Material for cages is
low-carbon steel or non-ferrous metal.
Special
Directions:
Easy to mount, but axial preloading during installation
is to be fully
considered.
