Product Description
High Precision Angular Contact NTN Ball Bearing QJ322 Series With Less Coefficient Friction
Detailed Product Description
Angular Contact Ball Bearing, which is similar to other ball bearings, angular contact ball bearing are compose of inner and outer races, ball complement and bearing cage; however, different to other ball bearings like a deep groove ball bearing, an angular contact ball bearing is designed with axially asymmetric race.
As a result, angular contact ball bearings are more suitable for supporting "combined loads" (loading in both the radial and axial directions); pure axial-load supporting in one direction is also possible. Generally speaking, the supporting capability for an axial load; and at the same time, the smaller the supporting capability for a radial load.
According to angular contact ball bearing manufacturers, single-row, and double-row angular contact ball bearings are both popular ones in the market. A single row angular contact ball bearing is suitable for carrying axial-load acting in one direction only; as a result, they are usually used in pairs or multi-arrangement in many applications. A double row angular contact ball bearing, however, is suitable for both an axial-load and a radial-load in both directions.
Feature:
Angular Contact Ball bearings are composed of Inner rings,Outer Rings,Balls and Cage.
1. Ring 's Material: Bearing Steel ZGCr15/GCr15
2. Balls' Material: Carbon chromium steel/Si3N4
3. Cage Material: Phenolic,Nylon,Plastic,Brass etc.
