Product description：

The spherical radial bearing has symmetric races to support radial loads while maintaining high speeds and rotational accuracy. It has a straight bore that fits conventional cylindrical shafts, and it has a C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion. Its steel cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise. This radial ball bearing is suitable for use in general purpose applications that primarily involve radial loads and minimal axial loads at relatively high rotational speeds. These include transmissions, motors, and pumps, among others.
