Spherical Roller Bearings SKF 22315 EK

The 22315 EK self-aligning roller bearing from SKF Rolling Bearings, with a 75 mm tapered bore and lubrication groove, offers high load-carrying capacity under shaft deflection.

The 22315 EK self-aligning roller bearing accommodates heavy radial and, at the same time, axial loads in both directions. Thanks to its self-aligning design, this bearing automatically compensates for misalignment and shaft deflection during operation. The open design, made from standard roller bearing steel (100Cr6), is rated for operating temperatures ranging from -30 to +200 degrees. A guided sheet steel cage maintains an even spacing between the rollers and contributes to smooth running.

In which installation situations does the 22315 EK self-aligning roller bearing compensate for misalignment?

It is primarily used for heavy combined loads where shaft deflection or misalignment between the shaft and housing occurs. The symmetrical rollers freely adjust themselves on the hollow spherical raceway of the outer ring. Thanks to the integrated lubrication groove and the lubrication holes in the outer ring, lubricant reaches directly between the roller rings. In combination with the Explorer design, the bearing unit is designed for demanding continuous loads.

What are the assembly benefits of the tapered bore with a 1:12 taper?

The tapered bore with a taper ratio of 1:12 facilitates assembly and disassembly on cylindrical or stepped shafts, for example by using a suitable mounting or withdrawal sleeve. By sliding the bearing axially onto the tapered seat to a defined position, the remaining radial clearance can be controlled during installation. With dimensional accuracy PN and running accuracy P5, the bearing meets high requirements for concentricity and vibration behaviour. The housing requires an external seal to protect the open bearing from contamination.
