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.

Types of Bearings | Uses & Working Mechanisms Explained - …

25/8/2020· Ball bearings provide very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races. They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion.
