SKF 61903-2RS1 Deep Groove Ball Bearing, ABEC 1 Precision, Double Sealed, Standard Cage, Normal Clearance, 17mm Bore, 30mm OD, 7mm Width, 522lbf Static Load Capacity, 9800lbf Dynamic Load Capacity

The SKF deep groove ball bearing is a double-sealed ball bearing with Annular Bearing Engineering Committee (ABEC) 1 precision and normal clearance. This ball bearing has a deep-groove geometry for high speeds and supporting both radial and axial loads. This bearing conforms to the precision standard ABEC 1 for performance within a narrow range of variation and has normal radial clearance for applications that do not involve thermal expansion or atypical precision. The standard cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. Seals on both sides of the bearing fasten to the outside ring and extend over the rolling elements to make contact with the inside ring, keeping out contaminants such as dirt and grime. The seals also hold in a high-quality lubricant applied at manufacture that will last the entire lifetime of the bearing, making it maintenance free. This deep groove ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy and stiffness at high rotational speeds. Such 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.SKF Group manufactures bearings and units, seals, mechatronics, and lubrication systems that meet International Organization for Standardization (ISO) 14001 and 9001, and Occupational Health and Safety Assessment Series (OHSAS) 18001 standards for quality assurance. The company, founded in 1907, is headquartered in Göteborg, Sweden.
