Tapered Roller Bearings SKF 30203

The SKF 30203 single-row tapered roller bearing, with dimensions of 17 × 40 × 13.25 mm, accommodates combined radial and axial loads.

The 30203 tapered roller bearing is used as a single-row rolling bearing in applications where combined radial and axial loads occur. Thanks to the line contact of the tapered rollers, this design can withstand high forces. Manufactured in the SKF Explorer design, the bearing features optimised surfaces on the raceways and roller end faces. The product comprises a complete bearing consisting of an inner ring with a set of rollers and the corresponding outer ring.

What is the 30203 tapered roller bearing suitable for?

The 30203 tapered roller bearing is typically used in industrial drives and shaft mountings subject to combined loads. As a single-row bearing can only accommodate axial forces in one direction, it is usually fitted in pairs in an O or X arrangement. In this way, two roller bearings positioned opposite each other transmit axial forces in both directions. The design retains its dimensional stability at operating temperatures ranging from -30 to +120 degrees.

What are the advantages of the sheet steel cage and the Explorer design?

The integrated sheet steel cage guides the rolling elements precisely and keeps the bearing stable even under demanding operating conditions. Together with tolerance class P0/PN (corresponding to ABEC 1), the unit meets industrial accuracy requirements. A key practical advantage lies in the separable design: the outer ring can be fitted separately from the inner ring with its roller cage. This simplifies installation in the housing and on the shaft, whilst allowing the bearing clearance to be adjusted during assembly.
