Spherical Roller Bearings SKF 22313 E

The SKF 22313 E self-aligning roller bearing, measuring 65x140x48 mm, offers reliable angular misalignment compensation and high load-carrying capacity for demanding industrial applications.

The SKF 22313 E self-aligning roller bearing is a double-row roller bearing designed for heavy mechanical loads. With an inner diameter of 65 mm, an outer diameter of 140 mm and a width of 48 mm, the bearing can simultaneously accommodate high radial forces and axial forces in both directions. Manufactured from standard 100Cr6 rolling bearing steel in the Explorer design, this rolling bearing is rated for operating temperatures from -30 to +200 degrees Celsius. It serves as a design solution for demanding shaft mountings in mechanical engineering.

What is the 22313 E self-aligning roller bearing suitable for in operation?

The 22313 E self-aligning roller bearing is suitable for designs where high loads act on shafts and where deflection or misalignment must be compensated for. The angularly adjustable design prevents harmful edge stresses inside the bearing should shafts deform under load. Typical applications include mountings subject to combined radial and axial forces as well as misalignment. Thanks to its open design, the bearing can be integrated into existing oil or grease lubrication systems.

What are the advantages of the lubrication groove and P5 running accuracy in the 22313 E model?

This bearing features a lubrication groove with lubrication holes in the outer ring, allowing lubricant to reach directly between the rows of rollers. This facilitates relubrication during maintenance. The integrated sheet steel cage guides the barrel-shaped rollers with low vibration, even during rapid changes in speed. Thanks to dimensional accuracy to PN class, combined with increased running accuracy to P5 class, the shaft runs particularly smoothly, whilst the standard radial bearing clearance is suitable for many standard fits.
