Spherical Roller Bearings SKF 22214 E

The SKF 22214 E spherical roller bearing, measuring 70x125x31 mm, offers high load-carrying capacity for heavy-duty industrial applications with varying misalignments.

The 22214 E self-aligning roller bearing is an open, double-row roller bearing designed for demanding industrial applications. It accommodates high radial forces as well as combined axial loads and automatically compensates for misalignment or shaft deflection. With key dimensions of a 70 mm bore, 125 mm outside diameter and 31 mm width, the component is suitable for standard installation spaces in mechanical engineering. SKF manufactures this model in the Explorer version from standard roller bearing steel (100Cr6), combined with a sheet steel cage.

Under what operating conditions does the 22214 E self-aligning roller bearing perform well?

Its use is particularly recommended for bearing arrangements subject to combined loads and design-related misalignments of the shaft. The self-aligning roller design compensates for misalignments between the inner and outer rings without causing excessive edge pressures. As this is an open bearing, lubrication is provided via an external housing system. The permissible temperature range extends from –30 to +200 degrees Celsius, thereby covering a wide range of thermal requirements.

What are the functions of the lubrication groove and P5 running accuracy?

The outer ring features a circumferential lubrication groove with integrated lubrication holes. This facilitates relubrication directly into the contact area of the rolling elements. In addition to the standard dimensional accuracy PN, this bearing offers enhanced running accuracy of class P5. This tighter manufacturing tolerance promotes smooth concentricity and reduces vibrations at high speeds. During installation, care must be taken to ensure an effective external housing seal, as the bearing is supplied from the factory without sealing washers.
