Ball bearing - Wikipedia

A 4-point angular contact ball bearing. An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that acts to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race.

Types of Bearings | Uses & Working Mechanisms Explained

Aug 25, 2020· The ball bearing’s small point of contact also means less friction. So there is less resistance to overcome and thus it is easier to achieve high speeds with these types of bearings. Roller Bearings. Roller bearings contain cylindrical rolling elements instead of balls as load carrying elements between the races. An element is considered a

Roller Bearings vs. Ball Bearings - What''s the Difference?

Jan 20, 2022· Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape.

1.TYPES AND FEATURES OF ROLLING BEARINGS

The inner and outer rings of four-point contact ball bearings are separable because the inner ring is split in a radial plane. They can take axial loads from either direction. The balls have a contact angle of 35° with each ring. Just one bearing of this type can replace a coination of face-to-face or back-to-back angular contact bearings.
