Tapered Roller Bearings SKF 33117

The SKF 33117 single-row tapered roller bearing, measuring 85 × 140 × 41 mm, accommodates high radial and unilateral axial loads in industrial applications.

The 33117 tapered roller bearing is designed as a complete rolling bearing and consists of an inner ring with a set of rollers and a matching outer ring. As a bearing in the SKF Explorer performance class, this design features a coordinated internal geometry for demanding operating conditions. The tapered arrangement of the rolling elements effectively transfers combined loads to the housing structure. Thanks to its open design, the lubricant can be freely selected to suit the operating conditions.

In which installation situations does the 33117 tapered roller bearing prove its worth?

This rolling bearing accommodates high radial forces in combination with axial forces acting in one direction. Typical applications are found in general mechanical engineering and gearbox construction where combined load directions occur. As a single tapered roller bearing supports axial forces in only one direction, it is usually fitted in pairs in an O or X arrangement with a second bearing positioned at right angles to it.

What features do the Explorer design and sheet steel cage offer?

The Explorer classification denotes a refined surface finish on the raceways, ensuring that the lubricating film remains stable even under varying loads. A dimensionally stable sheet steel cage guides the rolling elements precisely during rotational movement. The bearing is designed for a temperature range of -30 to +120 degrees. Manufacture to tolerance class P0/PN (corresponding to ABEC 1) ensures compliance with standard fit tolerances during installation and replacement.
