Spherical Roller Bearings SKF 22322 E

The 22322 E spherical roller bearing from SKF, measuring 110 × 240 × 80 mm, can accommodate heavy radial loads and compensates for misalignment.

The 22322 E self-aligning roller bearing is a double-row roller bearing made from standard bearing steel (100Cr6) for demanding mechanical applications. With a bore of 110 mm, an outer diameter of 240 mm and a width of 80 mm, the component automatically compensates for angular misalignment and deflection of rotating shafts. The open-type design in SKF Explorer quality combines proven bearing geometry with a robust sheet steel cage. The model is characterised by dimensional accuracy PN and enhanced running accuracy of class P5.

Under what operating conditions does the 22322 E spherical roller bearing operate?

It is primarily used where high radial forces act on rotating shafts and where misalignment or elastic deflection needs to be compensated for. Thanks to its permissible operating temperature range of –30 to +200 degrees, the bearing remains operational even under thermal stress. The open design allows for direct lubrication via centralised lubrication circuits using grease or lubricating oil.

What is the purpose of the P5 running accuracy and the lubrication groove on the 22322 E self-aligning roller bearing?

This model combines standard dimensional tolerances in accordance with Class PN with a tighter running accuracy tolerance in accordance with Class P5, which promotes smooth and low-vibration concentricity. Fresh lubricant is fed directly between the rollers and raceways via the lubrication groove integrated into the outer ring, complete with matching lubrication holes. This facilitates scheduled relubrication whilst the bearing is in operation. The design, featuring standard radial bearing clearance, provides a balanced operating clearance for standard fit conditions.
