Spherical Roller Bearings SKF 22211 EK

The 22211 EK self-aligning roller bearing from SKF combines a 55 mm tapered bore with P5 precision for demanding radial loads within a 55 x 100 x 25 mm installation space.

The 22211 EK self-aligning roller bearing is an open roller bearing made from standard bearing steel (100Cr6) in the Explorer performance class. Designed for heavy radial and axial loads in both directions, it automatically compensates for misalignment and shaft deflection. A sheet steel cage guides the rolling elements at operating temperatures ranging from -30 to +200 degrees. Thanks to its standard radial clearance, the component is suitable for standard operating conditions in continuous industrial use.

What is the 22211 EK self-aligning roller bearing suitable for in operation?

This bearing is used where shaft mountings must accommodate high radial forces whilst simultaneously compensating for angular misalignment between the shaft and housing. The design covers applications where shaft deflection or misalignment must be compensated for. Thanks to the increased P5 running accuracy combined with standardised PN dimensional accuracy, the unit operates with low vibration. The open design without an integrated seal allows direct connection to existing lubrication systems in the machine room.

What installation advantages does the tapered bore of the 22211 EK self-aligning roller bearing offer?

The tapered bore with a taper ratio of 1:12 facilitates mounting on clamping sleeves, withdrawal sleeves or directly onto tapered shaft journals. By sliding the bearing axially onto the shaft, fitters can precisely adjust the remaining bearing clearance in the system. The outer ring features a lubrication groove with lubrication holes. This allows lubricant to flow directly between the rows of rollers during operation, which facilitates targeted relubrication.
