FAG Angular Contact Ball Bearing -45mm ID x 100mm OD x 25mm (7309B-MP-UA)
- Ball Bearing
- Stainless Steel
The FAG single-row, open, angular contact bearing has asymmetric races with a 40-degree contact angle to support both axial and radial loads. It has a CN (normal) radial internal clearance for applications that do not involve thermal expansion, and 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 angular contact ball bearing is suitable for use in applications that involve combined radial and axial loads, and a need for high running accuracy and stiffness at high rotational speeds. These applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.

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 f r Normung (DIN) standards for quality assurance. The company, founded in 1883, is based in Schweinfurt, Germany.
