Tapered Roller Bearings SKF 33217

The SKF 33217 tapered roller bearing (85x150x49 mm) accommodates combined radial and axial loads and features a dimensionally stable sheet steel cage.

The 33217 tapered roller bearing is a single-row rolling bearing in the SKF Explorer performance class. Designed for demanding industrial applications, its design transmits radial and single-direction axial forces via tapered rollers and raceways. With an inside diameter of 85 mm, an outside diameter of 150 mm and a width of 49 mm, this unit is suitable as a complete tapered roller bearing for shaft support in mechanical engineering and gearbox construction.

What is the 33217 tapered roller bearing in the Explorer version suitable for?

Design engineers and maintenance technicians primarily use the 33217 tapered roller bearing for combined loads in machine and gearbox construction. As single-row tapered roller bearings, by design, can only accommodate axial forces in one direction, they are usually fitted in pairs in an X or O configuration with a second bearing positioned opposite. The modified contact geometry of the Explorer series promotes the formation of a load-bearing lubricating film and reduces load peaks near the edges.

What is important to consider regarding installation and tolerance class P0/PN?

This bearing is manufactured to the standard tolerance P0, which corresponds to tolerance class ABEC 1. The inner ring with roller cage and the flangeless outer ring can be fitted separately onto the shaft and housing. This simplifies the assembly process in the workshop. You can precisely set the desired bearing clearance during installation by carefully adjusting the bearing against the mating bearing. Careful alignment of the shaft helps to ensure smooth running. The operating temperature range is from -30 to +120 degrees.
