7338BDB Angular Contact Ball Bearing Black For Heavy Duty Applications

Product Specification

Angular contact ball Bearing 7338BDB

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis.This means that they are designed to accommodate combined loads,i.e.simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane,along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
 

Feature of Angular contact ball bearing:

Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.

Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.

Applications of Angular contact ball bearing: 
electric motors, automotive applications, home appliances, industrial equipment.
