SKF 61911 Radial Bearing Single Row Deep Groove Design ABEC 1 Precision Open ...

Description

SKF 61911 Radial Bearing, Single Row, Deep Groove Design, ABEC 1 Precision, Open, Normal Clearance, Standard Cage, 55mm Bore, 80mm OD, 13mm Width
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
Deep grooves support heavier loads than standard grooves and keep balls stable at high speeds
CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision
Standard cage evenly spaces the rollers for even load distribution and prevents to reduce friction, vibrations, and noise
The SKF 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 its deep grooves make it capable of supporting heavier loads than standard grooves and keeping balls stable for high speeds. It has a CN (normal) radial internal clearance for applications that do not involve thermal expansion, and its standard cage evenly spaces the rollers for even load distribution and prevents to reduce friction, vibrations, and noise. 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. Specifications Main bearing dimensions ISO 104:2002 Basic dynamic load ratings DIN ISO 281 Dimensional and geometric tolerances ISO 199:1997, tolerance class PN Through-hardening steel for inner and outer rings and rollers ISO 683-17 Pressed sheet steel for cage (DIN) EN 10111:1998 Load carrying capacity and life ISO 281:1990 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. 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.
