Four-Point Contact BearingsFour-Point Contact Ball Bearings

The inner ring is split radially into two pieces. Their design allows one bearing to sustain significant axial loads in either direction.The contact angle is 35°, so the axial load capacity is high. This type is suitable for carrying pure axial loads or combined loads where the axial loads are high.The cages are made of machined brass.
