QJ217 Four Point Angualr Contact Ball Bearing High Speed Separating Bearing

QJ217 four point  angualr contact ball bearing  high speed separating bearing 

Description:

4 point angular contact ball bearing is  separated type four-point contact ball bearing .

Steel ball and ring presents a four-point contact .

Can bear radial load , axial load , two-way can limit the axial displacement of two directions, but now the

specifications of the double row angular contact ball bearings occupy less axial space.

Specifications: 

Applications: 

They can be used for Transmission system,  Cranes ,

General engineering applications; Marine and Shipping;

The usage: Motors, Power tools, Household appliances, Trailers, Casters,
