Tapered Roller Bearings SKF 33109

The SKF 33109 tapered roller bearing, with dimensions of 45 × 80 × 26 mm, can withstand high combined radial and axial loads.

The 33109 tapered roller bearing is a single-row roller bearing from SKF in a standard design. With a bore of 45 mm, an outer diameter of 80 mm and a width of 26 mm, this design accommodates high radial and axial forces in one direction simultaneously. The sheet steel cage guides the tapered rollers precisely along the raceway. The product scope includes the complete tapered roller bearing, comprising the inner ring with roller cage and the matching outer ring.

In which applications is the 33109 tapered roller bearing used?

The 33109 tapered roller bearing is primarily used where high radial forces act in conjunction with unilateral axial loads. Typical applications include gearbox shafts, axle bearings, guide rollers and industrial drives. 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 to counteract opposing forces.

What distinguishes the Explorer version and the sheet steel cage?

This model is manufactured to the SKF Explorer performance class and features optimised contact surface geometry for targeted lubricant film formation. The integrated sheet steel cage keeps the rollers spaced apart and is suitable for operating temperatures ranging from –30 to +120 degrees. Thanks to its manufacture to standard tolerances (tolerance class P0 or ABEC 1), the bearing fits precisely into common standard fits used in mechanical engineering. Application-specific lubrication must be provided before commissioning.
