Spherical Roller Bearings SKF 22311 E

The SKF 22311 E spherical roller bearing, measuring 55 × 120 × 43 mm, offers a robust solution for high radial loads and angular shaft misalignment.

The 22311 E self-aligning roller bearing is an open rolling bearing designed for demanding industrial applications. Thanks to two rows of barrel-shaped rollers and the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. The SKF version is made from 100Cr6 bearing steel and features a dimensionally stable sheet steel cage. The unit can be used within a temperature range of -30 to +200 degrees. The mounting dimensions are 55 mm bore, 120 mm outside diameter and 43 mm width.

What is the 22311 E spherical roller bearing suitable for in operation?

This double-row roller bearing proves particularly effective where strong radial forces act on the shaft and misalignments arise due to manufacturing or load conditions. Typical applications include shaft mountings with elastic deflection or misalignment. As the design compensates for angular misalignment without a significant increase in friction, shafts remain correctly guided even under varying operating conditions. Design engineers use this design for demanding bearing arrangements subject to high radial loads.

What are the advantages of the lubrication groove and P5 running accuracy?

Lubrication grooves and lubrication holes integrated into the outer ring facilitate relubrication whilst the bearing is installed, as the lubricant is fed directly between the rows of rollers. The running accuracy to tolerance class P5, in conjunction with the standard dimensional accuracy PN, ensures low-vibration concentricity. As this is an open bearing without integrated sealing washers, the external sealing of the bearing housing must be adapted to the ambient conditions in order to prevent lubricant loss and the ingress of contaminants.
