Spherical Roller Bearings SKF 22214 EK

SKF 22214 EK self-aligning roller bearing (70x125x31 mm): An open roller bearing with a 1:12 tapered bore and P5 precision for demanding industrial applications.

The SKF 22214 EK self-aligning roller bearing, as a double-row roller bearing, accommodates high radial forces and combined axial loads simultaneously. The barrel-shaped rolling elements, in conjunction with the spherical outer ring raceway, automatically compensate for misalignment or shaft deflection. Manufactured in the Explorer version from 100Cr6 standard rolling-bearing steel, this open unit features a standard radial clearance and a sheet steel cage. An integrated lubrication system in the outer ring ensures uniform lubricant distribution across the entire operating temperature range from -30 to +200 degrees Celsius.

What loads and misalignments does the 22214 EK self-aligning roller bearing compensate for?

This double-row bearing is designed for applications involving high radial loads and axial forces acting in both directions. The spherical raceway in the outer ring dynamically compensates for angular misalignment between the shaft and housing without causing additional friction or edge pressure on the rollers. Thanks to its symmetrical design, the bearing reliably guides shafts in both axial directions. The lubrication groove with lubrication holes in the outer ring allows targeted relubrication directly at the contact zones as part of the ongoing maintenance process.

When is a 1:12 tapered bore recommended?

The suffix ‘K’ denotes a tapered bore with a ratio of 1:12. This design facilitates mounting on tapered shaft seats or, with the aid of mounting and withdrawal sleeves, on cylindrical shafts. During mounting, the radial bearing clearance is reduced in a controlled manner, allowing the desired fit to be set precisely. With dimensional accuracy class PN and increased running accuracy to tolerance class P5, this bearing is particularly suitable for assemblies that require smooth and low-vibration operation.
