Tapered Roller Bearings SKF 33019

The SKF 33019 tapered roller bearing combines a 95 mm bore with Explorer performance specifications for combined radial and axial loads in demanding industrial applications.

The 33019 tapered roller bearing is a single-row roller bearing to standard tolerance class P0/PN (ABEC 1), suitable for mechanical drives and shaft support. With key dimensions of 95 mm inner diameter, 145 mm outer diameter and 39 mm total width, the design accommodates both radial forces and axial forces from a single direction. As a complete tapered roller bearing, the unit comprises the inner ring with a set of rollers and the corresponding outer ring.

In which configurations is the 33019 tapered roller bearing fitted?

Due to its angular raceways, the bearing accommodates combined loads; however, it requires a mating bearing when used for axial guidance on one side only. Typical designs use paired mounting in an O or X arrangement to safely accommodate axial forces from both directions and guide the shaft precisely. Due to the line contact of the tapered rollers, the bearing can handle higher loads than comparable deep-groove ball bearings.

What are the distinctive features of the sheet steel cage and the Explorer design?

The SKF Explorer design is characterised by optimised raceway geometries and fine surfaces, which promote the formation of a stable lubricating film. The sheet steel cage guides the rolling elements precisely and is suitable for use in a temperature range from –30 to +120 degrees Celsius. As the bearing is of open design, the lubricant and housing seal can be selected to suit the specific application.
