High dimensions four-point contact ball bearings


High dimensions four-point contact ball bearings is a Single row bearing with one inner ring and one outer ring. The raceways are designed to support an axial load from both sides by themselves. It is smaller than the double row angular contact ball bearings along the axial direction. Typically its contact angle θ is 35° or 45° and the inner ring is made up of two parts. A large load carrying capacity due to the high number of balls is the trademark of this type of bearing. The two inner semi-rings and the outer ring together with the cage/balls group can be separately assembled.
