Tapered Roller Bearings SKF 30302

The SKF 30302 tapered roller bearing, measuring 15 × 42 × 14.25 mm, accommodates combined radial and axial loads in a single-row design.

This single-row 30302 tapered roller bearing consists, as a complete bearing, of an inner ring with a set of rollers and the matching outer ring. The design is particularly suitable for combined loads where radial forces act simultaneously with axial forces from a single direction. In SKF’s Explorer version, the roller bearing is characterised by a precisely matched internal geometry. As a result, the design promotes the formation of a clean lubricating film on the roller end faces and raceways during operation.

What is the 30302 tapered roller bearing suitable for?

The 30302 tapered roller bearing is primarily used where high radial forces are combined with axial forces acting from one side. As a single-row bearing can only accommodate axial forces in one direction, it is usually fitted in pairs in mechanical assemblies in an X or O arrangement, mirroring a second bearing. With a shaft bore of 15 mm and an outer diameter of 42 mm, this compact roller bearing offers high rigidity in a confined space.

What are the characteristics of the design with a sheet steel cage and standard tolerance?

The integrated sheet steel cage guides the tapered rolling elements evenly and keeps them spaced apart, which reduces friction and heat build-up. With tolerance class P0/PN (corresponding to ABEC 1), the component meets the standard accuracy requirements for industrial mechanical engineering. The permissible temperature range is from -30 to +120 degrees Celsius. As the inner ring, including the roller cage, and the outer ring can be fitted separately, the bearing clearance can be precisely adjusted during installation by means of back-alignment.
