SKF 6203/C2 Radial Bearing for Deep Groove Design

The SKF single-row, open radial bearing has symmetric races to support radial loads while maintaining high speeds and rotational accuracy. This bearing 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 C2 radial internal clearance for applications that need less clearance than CN (normal) clearance and do not involve thermal expansion, and its steel cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise. 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, such as transmissions, motors, and pumps.

Rolling bearings utilize rolling elements to maintain the separation between moving parts, reducing rotational friction and supporting radial and axial loads. These elements can be in the form of balls, cylinders, spheres, barrels, needles, spindles, or tapered shapes. All rolling bearings are either open, shielded, or sealed. Sealed bearings are pre-lubricated with oil or grease in the factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication based on usage. 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 find application in a wide range of industries, from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers.

The SKF Group, founded in 1907 and headquartered in Göteborg, Sweden, manufactures bearings and units, seals, mechatronics, and lubrication systems that meet the International Organization for Standardization (ISO) 14001 and 9001, as well as the Occupational Health and Safety Assessment Series (OHSAS) 18001 standards for quality assurance.
