Spherical Roller Bearings SKF 22315 E

The SKF 22315 E self-aligning roller bearing (75x160x55 mm) withstands heavy radial loads and compensates for misalignment thanks to its self-aligning design.

The 22315 E self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) with a bore of 75 mm, an outer diameter of 160 mm and a width of 55 mm. In SKF’s Explorer version, this design combines a high load-carrying capacity with compact installation dimensions. The design is particularly suitable for industrial applications where operational deflections or misalignments of the shaft relative to the bearing housing may occur.

What is the 22315 E self-aligning roller bearing suitable for in operation?

The rolling bearing is designed for use under high radial forces and shock loads. Thanks to the shared hollow-spherical raceway in the outer ring, the bearing self-aligns during operation, which effectively reduces edge pressures on the rolling elements. The design is suitable for demanding bearing arrangements where misalignment or elastic shaft deflection needs to be compensated for. The sheet steel cage guides the rolling elements cleanly along their raceways, even under varying speeds.

What are the key considerations regarding lubrication and tolerances for the 22315 E?

As an open rolling bearing, this design has no integrated seals, allowing lubricant to circulate freely and necessitating an external housing seal. A lubrication groove with lubrication holes in the outer ring allows direct access of lubricant to the rolling elements. The tolerance class combines dimensional accuracy in accordance with PN with increased running accuracy in accordance with P5 to ensure uniform concentricity. The bearing covers an operating temperature range from –30 to +200 degrees and has standard radial clearance.
