This SKF spherical thrust bearing has a steel cage and is suitable for operating conditions that experience high thrust loads and moderate radial loads, difficulty in establishing or maintaining housing alignment, or shaft deflection, such as in extruders and screw conveyors. This axial spherical roller bearing has a pressed steel cage that spaces the rollers for even load distribution and prevents contact to reduce friction, vibration, and noise. Its single roll of self-aligning barrel rollers arranged in a steep angular position on a raceway supports increased load ratings and higher rotational speeds, and compensates for misalignments, shaft deflections and housing deformations. This misalignment compensation allows weldments to be used for housing frames instead of castings, which reduces machining costs. This bearing can be used at operating temperatures from –22 to 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 thrust bearing is suitable for use in material handling equipment and metal mill work.

Roller 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.
