Spherical Roller Bearings SKF 22317 E

SKF 22317 E self-aligning roller bearing: An open self-aligning roller bearing with an 85 mm bore, 180 mm outer diameter and 60 mm width for demanding industrial applications.

The SKF 22317 E self-aligning roller bearing is designed for radial and combined loads in industrial machinery. As a double-row roller bearing, it automatically compensates for misalignment and shaft deflection during operation. This open roller bearing, made from standard bearing steel (100Cr6), measures 85x180x60 mm and features the SKF Explorer performance class. Fitted with a sheet steel cage and standard radial clearance, this version reliably withstands operating temperatures ranging from –30 to +200 degrees Celsius.

In which industrial applications does the 22317 E self-aligning roller bearing prove its worth?

This self-aligning roller bearing is suitable for applications involving high radial loads and combined forces, whilst also accommodating misalignment. Designs where shaft deflection may occur between bearing locations benefit from the angularly adjustable roller guidance. As the bearing is of open design, it can be integrated into existing oil or grease lubrication systems. The lubrication groove with lubrication holes in the outer ring ensures a uniform supply of lubricant directly into the bearing interior, which reduces friction and limits temperature rise during continuous operation.

What features do P5 running accuracy and the Explorer design offer in the 22317 E?

The Explorer version of the 22317 E combines dimensional accuracy in accordance with Class PN with increased running accuracy of Class P5. This tighter-toleranced running accuracy reduces vibrations and promotes smooth rotational movement. For lubrication, the component utilises the integrated lubrication groove and the holes in the outer ring. As the open bearing is not sealed, an external housing seal protects the interior from contamination. The integrated sheet steel cage reliably guides the rolling elements.
