Spherical Roller Bearings SKF 22208 E

The SKF 22208 E self-aligning roller bearing, measuring 40x80x23 mm, can withstand high radial loads and flexibly compensates for misalignment.

The SKF 22208 E self-aligning roller bearing is a double-row roller bearing designed for heavy mechanical loads. It supports shafts under combined radial and axial loads. Thanks to the hollow-spherical outer ring raceway, the bearing adjusts its angle, thereby compensating for misalignment or shaft deflection. The open design, made from standard bearing steel (100Cr6), allows for flexible use with oil or grease lubrication in a wide variety of industrial units.

What loads is the 22208 E self-aligning roller bearing suitable for?

The 22208 E self-aligning roller bearing accommodates high radial forces on rotating components whilst simultaneously compensating for misalignment. Typical applications are found in general mechanical engineering for shaft guides subject to high loads and prone to misalignment. Thanks to the integrated lubrication groove with lubrication holes in the outer ring, lubricant is fed directly between the rows of rollers. The component is designed for a temperature range of -30 to +200 degrees.

What is important to consider with the open design and P5 running accuracy?

As the bearing is designed as an open variant, the surrounding structure requires an external housing seal to protect against dirt and moisture. The dimensional accuracy PN complies with standard values, whilst the running accuracy P5 ensures enhanced concentricity. With standard radial bearing clearance, the component is suitable for typical fit conditions and moderate operating temperatures. The sheet steel cage guides the barrel-shaped rollers in an orderly manner along the raceways during operation.
