BEARINGS PRODUCTION RANGE

FOUR-POINT ANGULAR CONTACT BALL BEARINGS
RKB 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.
To prevent rotation of the outer ring (when split inner ring) all the bearings with outside diameter over 160 mm
are provided with locating slots (suffix N).
The main boundary dimensions are in accordance to ISO 15.
The tolerances have values conform to ISO 492 and the normal class is for RKB standard production.
The fitted cage is machined brass centered on outer ring for the standard common type QJ with split inner ring.
RKB produces these bearings with normal axial internal clearance measured before mounting under zero
measuring loads, but most sizes can also be supplied with greater or smaller clearance to special order.
