Spherical Roller Bearings SKF 22320 EK

The SKF 22320 EK self-aligning roller bearing, with a 100 mm bore and an outer diameter of 215 mm, offers high load-carrying capacity for heavy-duty industrial applications.

The SKF 22320 EK self-aligning roller bearing is a double-row, open roller bearing designed for combined radial and axial loads. The 100Cr6 bearing steel and the robust sheet steel cage allow for a wide operating temperature range from -30 to +200 degrees. Thanks to the hollow-spherical outer ring raceway, the bearing automatically compensates for misalignment and shaft deflection during operation.

Under what operating conditions is the 22320 EK self-aligning roller bearing required?

This bearing is primarily used in heavily loaded bearing arrangements where high radial forces are present and misalignment between the housing and the shaft must be compensated for. Thanks to the integrated lubrication groove with lubrication holes in the outer ring, you can apply grease or lubricating oil directly between the two sets of rollers. The open design, with a width of 73 mm and standard radial clearance, allows for direct integration with external housing seals and lubrication systems.

What installation advantages does the 1:12 tapered bore offer?

The suffix EK denotes a tapered inner ring bore with the standardised taper ratio of 1:12. This design facilitates installation on tapered shaft seats as well as mounting using clamping or withdrawal sleeves on cylindrical shafts. You can precisely set the required bearing clearance by axially sliding the bearing onto the shaft. In combination with the increased running accuracy P5 and standard dimensional accuracy PN, the bearing ensures smooth, low-vibration operation.
