Angular contact ball bearing
Angular contact ball bearing
1) The scope of processing :
Single-row angular contact ball bearing :φ140~φ1500mm
Double-row symmetric angular contact ball bearing: φ140~φ5000mm
2) Characteristics:
Angular contact ball bearing with contact angle is applicable to high speed and high precision rotary, which can bear combined load.
Standard contact angle is 15,25 and 40 respectively configuring in post position with code “C”,”AC” and “B”. The more contact angle is, the larger axial load bearing capacity is , the smaller contact surface is ,the much more convenient high speed rotary is.
This bearing creates axial thrust load when being forced by radial load , thus it is configured (or combined) face to face or back to back.
