This SKF shaker screen spherical roller bearing has a brass cage, a C4 radial clearance, a P5 precision outer ring with lubrication groove and three oil holes, and a straight bore suitable for applications that support high radial and oscillating axial loads, such as in vibrating screens. The machined brass cage spaces the rollers for even load distribution and prevents contact to reduce friction, vibration, and noise. 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 bearing conforms to Deutsches Institut für Normung (DIN) P5 precision standard for performance within a narrow range of variation and its C4 radial clearance is larger than CN and C3 for applications where impact loads and vibration are severe, both the inner and outer rings are tight fitted, or thermal expansion is a factor. This roller bearing's straight bore fits conventional cylindrical shafts. This roller bearing is intended for interchangeability and meets 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 shaker screen spherical roller bearing is suitable for use in aggregate industry applications such as vibrating screens, jaw crushers, impactors, cone crushers, and conveyors.

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.
