Spherical Roller Bearings SKF 22314 EK/C3

The SKF 22314 EK/C3 self-aligning roller bearing with a tapered bore (70x150x51 mm) automatically compensates for misalignment and can withstand very heavy radial loads.

The SKF 22314 EK/C3 self-aligning roller bearing is a double-row, open roller bearing designed for demanding operating conditions. With dimensions of 70 mm bore, 150 mm outer diameter and 51 mm width, the bearing can handle high radial and combined forces. The spherical outer ring raceway allows for angular self-alignment, thereby compensating for shaft deflection during operation without increased edge pressure. The sheet steel cage guides the symmetrical sets of rollers evenly.

For which operating conditions is the 22314 EK/C3 self-aligning roller bearing suitable?

This bearing design is preferred for applications where shaft deflection and high shock loads occur. The open design, made from standard rolling-element bearing steel (100Cr6), is rated for temperatures ranging from –30 to +200 degrees. Lubricant is fed directly between the rows of rollers via the integrated lubrication groove and lubrication holes in the outer ring. This facilitates targeted relubrication whilst the bearing is in operation.

What are the advantages of the tapered bore and C3 clearance?

The suffix ‘EK’ denotes the tapered inner ring bore with a 1:12 taper. This allows mounting directly onto a tapered shaft seat or, using a clamping or withdrawal sleeve, onto cylindrical shafts. In conjunction with the slightly increased radial bearing clearance C3, the required operating clearance is maintained even after radial press-fitting and during operation-induced heating. Furthermore, this design offers increased running accuracy to tolerance class P5 with standard dimensional accuracy PN.
