Tapered Roller Bearings SKF 33209

The SKF 33209 tapered roller bearing accommodates combined radial and axial loads and has compact dimensions of 45 × 85 × 32 mm.

The 33209 tapered roller bearing is a single-row roller bearing in a standard open design, which accommodates high radial forces in combination with axial forces acting in one direction. SKF manufactures this complete tapered roller bearing in the Explorer design with the standard tolerance class P0/PN or ABEC 1. With a bore of 45 mm, an outside diameter of 85 mm and a width of 32 mm, the component fits into standardised housing fits. The inner ring with roller cage and the outer ring can be fitted separately.

In which assemblies is the 33209 tapered roller bearing used?

Due to the line contact between the tapered rollers and the raceways, the bearing can withstand high loads. The roller bearing is used in mechanical designs subject to combined loads, where shafts must be guided precisely both radially and axially. As single-row designs, by their very nature, can only accommodate axial forces in one direction, they are usually fitted in pairs in an O or X arrangement with a second bearing positioned opposite. This allows for precise adjustment of the desired bearing clearance during operation.

What are the distinctive features of the cage and temperature range of this Explorer version?

This bearing features a dimensionally stable sheet steel cage, which guides the tapered rollers evenly and promotes the flow of lubricant. The permissible operating temperature range extends from –30 to +120 degrees Celsius, making the bearing suitable for demanding industrial thermal environments. The SKF Explorer design features an optimised surface finish on the raceways. During assembly, you can precisely adjust the required preload or operating clearance by adjusting the axial alignment of the two rings.
