Angular Contact Ball Bearings
Angular Contact Ball Bearings
The contact angle is defined as the angle between the line joining the point of contact between the raceway and ball at the radial plane. In addition to the radial loads, because of contact angle, these bearings can also support axial load. The axial load carrying capacity of these bearings increases as the contact angle.
Due to lower shoulder, number balls can be accommodated in these bearings. This increases the radial load carrying capacity.
Single Row Angular Contact Bearing
It can support axial load in one direction only. To counter axial load from other direction two single row bearings are adjusted depending upon the direction of axial force. To transfer load acting on the bearing, they are manufactured by different contact angles as given below.
Double Row Angular Contact
Double row angular contact ball bearings consists of inner, outer rings, ball and cage assemblies with sheet steel or polyamide cage. The bearings are available in open and sealed designs. Bearing can support radial and axial loads in both the directions due to the raceway geometry and the two rows of balls.
Double row angular contact bearing design is similar to single row. Design d on back to back arrangement. They can support load in both the direction. Because of the second row the load carrying capacity is enhanced. The contact angle is 250. The bearings are available in shield and rubber seals.
