5P-8353: 69.85mm Bore Diameter Needle Roller Bearing

A Deep Groove Ball Bearing is a type of rolling contact bearing which consists of an inner race that is mounted on the shaft or journal and an outer race that is carried by the housing or casing. In between the inner and outer race, rolling elements i.e. balls are there. Several balls or rollers are used and these are held at proper distances by retainers so that they do not touch each other. The radius of the ball is slightly less than the radii of curvature of the grooves in the races providing point contact between the balls and the races. Therefore, the balls and the races may roll freely without any sliding. Attributes: • High load-carrying capacity in the radial as well as the axial direction • Excellent performance in high-speed applications • Less frictional loss and therefore low resultant temperature rise Applications: A Deep Groove Ball Bearing is used to provide relative motion between the brake housing and shaft.
