Self-aligning bearing for applications subject to shaft deflections or misalignments between the shaft and housing
Tapered bore with 1:12 taper for compensating for a flexing shaft or fitting to a tapered shaft
Contact seals on both sides of the bearing keeps lubricant in and contaminants out
Glass fiber reinforced polyamide 66 plastic cage evenly spaces balls for reduced friction, vibration, and noise
C3 radial internal clearance is larger than normal allowing for thermal expansion
This FAG double-row self-aligning ball bearing is double-sealed, and has a tapered bore, polyamide/nylon cage, and C3 clearance rating. It is suitable for applications supporting moderate radial loads and moderate to low thrust loads. This bearing has concave sphered housing rings to compensate for static angular misalignments between the shaft and housing in applications subject to shaft deflections or mounting errors. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds. This bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. The bearing has a tapered bore with a standard 1:12 taper to compensate for shaft deflection or to mount on a tapered shaft using an interference fit. Contact seals on both sides of the bearing keep out contaminants such as dirt and grime and hold in lubricant applied at manufacturing that lasts the lifetime of the bearing. This bearing has an injection-molded snap-type cage made of glass fiber reinforced polyamide 66 to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). The bearing has a C3 radial internal clearance designation to indicate that the radial slack between the inner and outer rings is greater than the standard CN (normal) clearance. It allows for thermal expansion as the bearing supports radial loads and its balls, operating in the deep raceway geometry, reduce rotational friction. Additionally, this bearing is produced to PN (normal) tolerances in accordance with Deutsches Institut für Normung (DIN) 620-2 standards for quality assurance. This self-aligning ball bearing is for use in commercial and industrial applications including film processing equipment, office automation, vertical spinning equipment, and industrial countershafts, 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 für Normung (DIN) standards for quality assurance. The company, founded in 1883, is based in Schweinfurt, Germany.
