Spherical Roller Bearings SKF 22316 E

The SKF 22316 E self-aligning roller bearing, with an 80 mm bore, 170 mm outer diameter and 58 mm width, can accommodate high radial and axial loads.

The SKF 22316 E self-aligning roller bearing is a double-row roller bearing in the Explorer performance class, designed for demanding industrial applications. Manufactured from standard rolling-bearing steel (100Cr6), this design combines a cylindrical 80 mm bore with a sheet steel cage. The outer ring’s spherical raceway automatically compensates for misalignment and shaft deflection during operation. As an open bearing, it can be flexibly integrated into oil- or grease-lubricated assemblies.

What is the 22316 E self-aligning roller bearing suitable for?

Design engineers and maintenance personnel select this design primarily for bearing arrangements subject to very high radial forces and axial forces acting from both sides. Typical applications include heavy-duty mechanical assemblies and shaft bearings where deflection or misalignment is to be expected. As the bearing compensates for static and dynamic misalignments between the inner and outer rings, it counteracts impermissible edge stresses on the roller bodies should shafts deform elastically under load.

What is the function of the lubrication groove and P5 running accuracy in the 22316 E?

Lubricant is fed directly between the rows of rollers via the integrated lubrication groove with lubrication holes in the outer ring. This facilitates relubrication whilst the bearing is installed. Whilst the dimensional accuracy complies with standard class PN, the bearing offers increased running accuracy in accordance with tolerance class P5. This reduced radial runout error ensures smooth running at operating temperatures ranging from –30 to +200 degrees Celsius.
