About SKF 6321/C3 Radial Bearing, Single Row, Deep Groove

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 C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion, and its steel cage evenly spaces the rollers for even load distribution and prevents contact 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.SpecificationsMain bearing dimensionsISO 104:2002Basic dynamic load ratingsDIN ISO 281Dimensional and geometric tolerancesISO 199:1997, tolerance class PNThrough-hardening steel for inner and outer rings and rollersISO 683-17Pressed sheet steel for cage(DIN) EN 10111:1998Load carrying capacity and lifeISO 281:1990System for creating part numbers for rolling bearingsDIN 623-1Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads.
