Spherical Roller Bearings SKF 22214 EK/C3

The SKF 22214 EK/C3 self-aligning roller bearing, with a 70 mm bore, 125 mm outer diameter and C3 clearance, offers high load-carrying capacity under misalignment conditions.

The SKF 22214 EK/C3 self-aligning roller bearing is designed for demanding industrial applications involving combined loads. With main dimensions of 70x125x31 mm, this double-row roller bearing can accommodate very high radial forces as well as axial forces on both sides. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. The open component is made of standard roller bearing steel (100Cr6) and is designed for a temperature range of -30 to +200 degrees Celsius.

What loads can the 22214 EK/C3 self-aligning roller bearing withstand?

This bearing design is primarily used where high combined forces are present. Wherever shaft deflection occurs or misalignment between housings is unavoidable, the bearing counteracts internal stresses. The integrated lubrication groove with lubrication holes in the outer ring facilitates relubrication whilst the bearing is in operation. The sheet steel cage guides the roller sets accurately, even under shock loads.

When is the combination of a tapered bore and C3 clearance advantageous?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design allows mounting directly onto a tapered shaft seat or, using a shrink sleeve, onto cylindrical smooth shafts. During assembly, the inner ring expands, which reduces the radial bearing clearance. The factory-increased C3 bearing clearance helps to ensure that the required operating clearance is maintained after press-fitting and during operation-induced heating. The running accuracy to tolerance class P5 ensures low-vibration operation.
