Tapered Roller Bearings SKF 32940

The single-row SKF tapered roller bearing 32940 (200 × 280 × 51 mm) accommodates radial and unilateral axial loads and is designed for gearbox applications involving combined forces.

The 32940 tapered roller bearing is a separable rolling bearing for mechanical drive systems. With an inner diameter of 200 mm, an outer diameter of 280 mm and a width of 51 mm, the component transmits combined loads. The line contact of the tapered rolling elements simultaneously supports radial forces and axial forces from one direction. As a complete bearing in the SKF Explorer design, the unit is designed for demanding conditions in continuous industrial operation.

In which types of bearing arrangements is the 32940 tapered roller bearing used?

This single-row roller bearing is used in industrial gearboxes and large mechanical drives. As single-row tapered roller bearings, by their design, only transmit axial forces in one direction, designers usually fit a second bearing in a mirror-image configuration as a counter-guide. This paired arrangement supports the shaft guides and ensures precise guidance. The 32940 tapered roller bearing provides a solution where high radial and axial forces act simultaneously on the shaft.

What role do the sheet steel cage and tolerance class P0/PN play?

The integrated sheet steel cage guides the rolling elements precisely and maintains a stable lubricant requirement. The bearing covers a temperature range from –30 °C to +120 °C, enabling operation under varying thermal conditions. Manufacture to tolerance class P0/PN (equivalent to ABEC 1) defines standard tolerances for concentricity and dimensional accuracy in industrial fits. During installation, the inner ring, together with the roller set, and the outer ring can be fitted separately before the axial bearing clearance is adjusted.
