Thrust Roller Bearings

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 automobile,machine tool,metallurgical and textile machinery;motor,driving shaft,gearbox and other location & supporting location.

Type of Designs:

For bearing rolling body,various structures of thrust balls,needle rollers and cylindrical rollers are available.

For cage, material 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 bade on GB/T307

Machined cylindrical roller precision is class III(ISO GB/T4661)

Mutual difference of needle roller diameter is 2 um,and the precision is class G2(ISO GB/T309)

Material

   Material for rolling body is GCr15 bearing steel,quench-hardening HRC60-65

   Material for thrust washer is GCr15 bearing steel,quench-hardening HRC60-65

Material for punched parts is quality low-carbon steel

Material for cages is low-carbon steel or non-ferrous metal

Special Direction

   Easy to mount,but axial pre loading during installation to be fully considered
