Paired bearings are used when a single bearing cannot provide the required radial and axial load capacity or rigidity. Common CA, CB and CC universal pairs can be installed in tandem, face-to-face or back-to-back arrangements.

Pairing changes axial clearance, stiffness and load distribution. The correct arrangement depends on load direction, speed, temperature, shaft expansion and the required locating function.

BNJ can recommend the pair, preload and fit for your equipment conditions.
