Four-point contact ball bearings

The inner and outer rings of four-point contact ball bearings are separable, because the inner ring is split along a radial plane. They can take axial loads from either direction.

The balls have a contact angle of 35° with each ring, so the axial capacity is high. This type is suitable for carrying pure axial loads or combined loads where the axial loads are high.

 

Just one bearing of this type can replace a combination of face-to-face or back-to-back angular contact bearings.
