About SKF 22212 EK/C3 Explorer Spherical Roller

This SKF Explorer spherical roller bearing has a steel cage, a C3 radial clearance, an outer ring with center lubrication groove and three oil holes, and a 1:12 tapered bore suitable for applications that support radial and oscillating axial loads, such as in a belt conveyor system. The two-piece pressed steel window-type cage has high wear resistance and spaces the rollers for even load distribution and prevents contact to reduce friction, vibration, and noise, and the cage is guided on the inner ring. This roller bearing's C3 radial clearance is larger than normal for applications where impact loads and vibration are severe, or thermal expansion is a factor. The bearing's 1:12 tapered bore compensates for flexing shafts and fits tapered shafts. This bearing has two rows of symmetrically arranged rollers oriented on a concave raceway, which allow self-realignment and compensate for static and dynamic alignment errors. The bearing has a maximum operating temperature of 392 degrees F. This roller bearing is intended for interchangeability and meets Deutsches Institut für Normung (DIN) standards for parts numbering, bearing dimensions, load ratings, tolerances, and clearances. It meets International Standards Organization (ISO) standards for hardening of bearing rollers and rings. This spherical roller bearing is suitable for use in material handling equipment, electric generators, and machine tools.SpecificationsMain bearing dimensionsDIN 635-2Basic dynamic load ratingsDIN ISO 281Dimensional and geometric tolerancesDIN 620-2, (ISO 492) tolerance class PNSteel composition for inner and outer rings and rollersISO 683-17System for creating part numbersDIN 623-1Roller 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 roller 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 manufactures bearings, seals, and lubrication systems for automotive, OEM, energy, and other and industrial applications. The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
