Spherical Roller Bearings SKF 22322 EK/C3

The SKF 22322 EK/C3 self-aligning roller bearing (110x240x80 mm), with a tapered bore, C3 clearance and a sheet steel cage, offers high load-carrying capacity even with misalignment.

The SKF 22322 EK/C3 self-aligning roller bearing accommodates heavy radial loads as well as axial forces in both directions. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation. The version made from standard 100Cr6 bearing steel covers a temperature range from -30 to +200 degrees. With dimensional accuracy class PN and enhanced running accuracy to class P5, this open bearing meets demanding concentricity requirements.

What is the 22322 EK/C3 self-aligning roller bearing suitable for in industrial applications?

Design engineers and maintenance personnel use this size primarily in heavy-duty industrial gearboxes and high-load shaft bearings. Wherever high impact loads occur or housing components deform slightly under load, the angle-adjustable design helps to prevent edge stresses. The integrated lubrication groove, together with the lubrication holes in the outer ring, ensures a direct and even supply of grease or oil to the roller sets during maintenance.

What advantages do tapered bores and C3 clearance offer during assembly?

The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design allows for mounting directly onto tapered shaft seats or, using mounting and withdrawal sleeves, onto cylindrical shafts. When slid onto the tapered seat, the inner ring expands in a controlled manner, causing the radial bearing clearance to decrease in a controlled way. The factory-set increased bearing clearance class C3 ensures that sufficient operating clearance is maintained after the radial interference fit has been achieved and under operating conditions where the bearing heats up.
