Product Features
Axially symmetric races to support radial loads while maintaining high speeds and rotational accuracy
Conforms to ABEC 1 precision standard for performance within a narrow range of variation
C4 radial internal clearance for radial slack between the inner and outer rings is greater than CN (normal) and C3 to compensate for thermal expansion
Brass cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise
Open bearing for lubrication in place and for use in applications with little exposure to dirt, grime, debris, and other contaminants
Product Description
The FAG single-row, open radial bearing has symmetric races to support radial loads while maintaining high speeds and rotational accuracy. It conforms to the precision standard Annular Bearing Engineers Committee (ABEC) 1 for performance within a narrow range of variation, and it has a C4 radial internal clearance for radial slack between the inner and outer rings that is greater than C3 to compensate for thermal expansion. Its brass cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise, and extending the life of the bearing. It has an open configuration for lubrication in place and applications involving negligible exposure to dirt, grime, debris, and other contaminants. 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.

System for creating part numbers for rolling bearings DIN 623-1
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
FAG manufactures a variety of bearings that meet International Organization for Standardization (ISO) and Deutsches Institut für Normung (DIN) standards for quality assurance. The company, founded in 1883, is based in Schweinfurt, Germany.
