Journal Bearing Inner Rings

Journal Bearing Inner Rings are made from hardened rolling bearing steel and have precision ground or machined raceways. Ideal applications for using Journal Bearing Inner Rings include:

1 When in order to allow larger axial displacements of the shaft in relation to the housing, needle roller bearings must be combined with wider Journal Bearing Inner Rings.

2 Where the shaft cannot be used as a raceway (such as for drawn cup needle roller bearings with open ends; drawn cup needle roller bearings with closed end; needle roller and cage assemblies; and needle roller bearings).

3 When optimal running surfaces are necessary in order to seal lips.

Over 260 models between two different series of  Journal Bearing Inner Rings are available from AST Bearings and are defined by their dimensional characteristics (metric versus inch).
