Tapered Roller Bearings SKF 33207

The SKF 33207 tapered roller bearing, with a 35 mm bore, 72 mm outer diameter and 28 mm width, offers a robust solution for combined loads.

The single-row 33207 tapered roller bearing accommodates high radial and axial forces simultaneously. As a complete tapered roller bearing in SKF’s Explorer series, this design features optimised contact geometry of the raceways. The integrated sheet steel cage guides the tapered rollers precisely and allows for an operating temperature range of -30 to +120 degrees. The open bearing is designed for operation in lubricated housings.

What is the 33207 tapered roller bearing suitable for in practice?

This rolling bearing is used where significant radial loads are combined with unidirectional axial forces. Typical applications include rotating shafts and bearing arrangements subject to combined loads. As a single-row bearing can only accommodate axial forces in one direction, in mechanical engineering the component is usually mounted in pairs, with a second bearing fitted in a mirror-image configuration. This stabilises the shaft in both axial directions.

What role does the Explorer version with a sheet steel cage play?

Manufacture to tolerance class P0/PN (corresponding to ABEC 1) defines standardised mounting dimensions for direct installation. The dimensionally stable sheet steel cage maintains a uniform spacing between the rollers across the entire temperature range. As the outer ring is removable, the inner ring and roller set can be fitted separately. During design, care must be taken to ensure adequate lubrication and external sealing against contamination.
