FOUR-POINT ANGULAR CONTACT BALL BEARINGS
KORTON four-point angular contact ball bearings are single row bearings where the raceway is designed to accommodate significant axial loads in both directions.
Generally they have contact angle of either 35° or 45°.
They need less axial space than double row or paired angular contact ball bearings.
The four-point contact ball bearings have a split two-part inner (bearing designation QJ) or outer (bearing designation Q) ring, allowing a large number of balls to be incorporated, thus providing a high load carrying capacity. The bearings are of separable design of the parts.
