Duplex bearings | Principle Engineering

Duplex bearing O (<>) arrangement: Back to back (designation –1 and DB for spindle bearings) With this bearing configuration the inner rings are designed to be clamped together. The contact angle load path between the outer ring raceway, the ball and the inner ring curvature diverge, which results in maximum stability and stiffness against any moment loading.
