Machined Type Needle Roller Bearing Inner Ring (JR)

  • Inner Ring.

About Inner Ring Metric Series

  • When it becomes impractical to meet the shaft raceway design requirements (hardness, case depth, surface finish, etc.) outlined in the engineering section of this catalog, standard inner rings may be used with metric series have drawn cup bearings.
  • It is suggested that when metric series inner rings are used with metric series have drawn cup bearings, they should be mounted with a loose transition fit on the shaft using g5 shaft diameter tolerance.
  • The inner ring should be end-clamped against a shoulder.
  • If a tight transition fit must be used (shaft diameter tolerance h5) to keep the inner ring from rotating; relative to the shaft, the inner ring outer diameter, as mounted, must not exceed the raceway diameter required by the drawn cup; bearing for the particular application.
  • In case the outer diameter of the inner ring, when mounted on the shaft, exceeds the required raceway diameter for the matching drawn cup bearing, it should be ground to proper diameter while mounted on the shaft.
  • When such exacting close control of radial internal clearance is not required the user may select g6 or h5 shaft diameter tolerances.

About Drawn Cup Needle Roller Bearing

  • Drawn cup needle roller bearings support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers.
  • The small cross-section of the drawn cup bearing provides high load-carrying capability with a minimum required space.
  • Drawn cup bearings are easily installed with a press fit in the housing.

Features

  • Available in two basic designs: full complement and caged.

Benefits

  • Full complement bearings handle high radial load-carrying capability.
  • Caged bearings provide high speed and maximum lubricant-retention capability.
