Spherical Roller Bearings SKF 22217 E

The SKF 22217 E self-aligning roller bearing (85x150x36 mm) withstands heavy radial loads and compensates for misalignment with angular movement whilst in operation.

The 22217 E self-aligning roller bearing is a double-row roller bearing from the SKF Explorer series with a bore diameter of 85 mm, an outer diameter of 150 mm and a width of 36 mm. It compensates for misalignment between the shaft and housing with angular movement. Manufactured from standard 100Cr6 rolling bearing steel and featuring a dimensionally stable sheet steel cage, this rolling bearing is designed for operating temperatures ranging from –30 to +200 degrees. The open bearing is suitable for machine components where high radial forces and axial guidance forces acting in both directions are exerted on the bearing seat.

For which operating conditions is the 22217 E self-aligning roller bearing suitable?

This self-aligning roller bearing is primarily used in industrial drives and heavy-duty gearbox assemblies where shaft deflection or misalignment occurs. The barrel-shaped rollers and the hollow-spherical outer ring raceway allow the rolling elements to self-align freely. As a result, the component distributes heavy radial and axial loads evenly without generating disruptive edge stresses. Furthermore, the design with standard radial clearance ensures low-vibration operation at typical operating temperatures.

What functional advantages do the lubrication groove and P5 running accuracy offer?

The outer ring is fitted with a lubrication groove and lubrication holes. This feature facilitates the supply of grease or lubricating oil directly into the centre of the rolling elements, enabling you to carry out relubrication during operation in a systematic manner. The increased running accuracy of tolerance class P5, combined with standard dimensional accuracy PN, results in particularly smooth concentricity. When designing the application, please note that the open bearing requires a housing seal to be fitted on site to prevent the ingress of dirt particles.
