Spherical Roller Bearings SKF 22216 E

The SKF 22216 E self-aligning roller bearing (80x140x33 mm) compensates for angular misalignment and withstands heavy radial loads during operation.

The 22216 E self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) for demanding industrial applications. With a bore of 80 mm, an outside diameter of 140 mm and a width of 33 mm, this open bearing corresponds to SKF’s Explorer series. The design combines PN dimensional accuracy with a finer P5 running accuracy. This makes the bearing suitable for industrial shaft support applications where misalignment occurs and uniform concentricity is required.

What is the 22216 E spherical roller bearing suitable for in industrial applications?

This bearing accommodates combined loads with a predominant radial component and compensates for both static and dynamic misalignments of the shaft. Typical applications include heavily loaded shaft mountings with deflection or misalignment. Thanks to the hollow-spherical outer ring raceway, the barrel rollers can adjust their angle without causing additional edge pressure on the rolling elements.

What role do the lubrication groove, cage and P5 running accuracy play in the selection process?

The outer ring features a lubrication groove with lubrication holes, which facilitates targeted relubrication during operation. As this is an open design, protection against contamination is determined by the external lubricant and housing seals. The integrated sheet steel cage guides the rollers at operating temperatures ranging from –30 to +200 degrees. The P5 tolerance class for running accuracy reduces runout deviations compared with standard tolerance alone.
