7900-7309 Full Ceramic ZRO2 SI3N4 Angular Contact Ball Bearings

7900-7309 full ceramic ZRO2 SI3N4 angular contact ball bearings 

Angular contact ball bearing with contact angle is applicable to high speed and high precision rotary, which can bear combined load.

1. Single row and combined angular contact ball bearing

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. 

2. Double row angular contact ball bearing

Double row angular contact ball bearing can be subinitted radial and acial louding limit speed is quite high, it is non-separated type of bearing has high rigid can be submitted doubk direetion of axial load, ball bearing

This kind of bearing outer ring of locking in on the inner and outer rings can not be separated, can be combined radial and axial loads and axial loads in one direction. Axial load capacity determined by the contact angle, the contact angle is large, the ability to withstand high axial loads. This kind of bearing shaft or housing to limit axial displacement in one direction.
