Four-point contact ball bearings are single-row angular contact types, with raceways designed to accommodate axial loads in both directions.
They require less axial space than the double-row oblique types.
Those listed in the tables generally have a contact angle of 35° or 45° and a two-part inner ring.
A large number of balls gives them a high load capacity.
They are separable, that is, the two internal semi-rings and the external one with the relative ball cage group can be mounted separately.
