Thrust needle bearing and washers:
1.Featuring compact structures 2.capability of bearing single-direction axial force
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 (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.
