RBC Heim Ball Bearing RF81812PP Flanged, Double Sealed, 0.500" Bore, 1.125 OD, 0.375" Width

This RBC Heim RF81812PP single-row radial ball bearing has a flanged housing and double seals, and is suitable for applications that support high radial loads at speeds up to 1000 rpm. Its deep ball grooves in both races support high radial and axial loads and its straight bore fits conventional cylindrical shafts. This case-hardened steel bearing has a 0.500" bore diameter, a 1.125" outside diameter, and a 0.375" width. Its raceways are precision ground, allowing higher speeds and creating lower friction than comparable-sized roller bearings. Synthetic rubber seals on both sides of the bearing keep out contaminants such as dirt and grime and hold in the lubricant applied at manufacture. This radial ball bearing is suitable for use in commercial and industrial applications including household appliances, power tools, wheels, and lift mechanisms.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.RBC Bearings manufactures bearings, pins, rollers, and shafts, and other products for industrial and aerospace applications under the RBC, Nice, Heim, Unibal, and Spherco brands. The company, founded in 1919 and headquartered in Oxford, CT, meets International Organization for Standardization (ISO) standards 9001:2008 and ISO/TS 16949:2009.
