3D CAD and 2D Drawings

Find and download 3D CAD and 2D drawings for key Timken products.

  • Ideal choice where the shaft is not practical to use as inner raceway.
  • Designed to meet established inch tolerances.
  • Maximum shaft fillet radius cannot exceed inner-ring bore chamfer as shown.
  • Optional centralized lubrication groove (bore) or through hole available – specify when ordering.
  • Designed to be axially clamped against shoulder for loose transition fit on shaft.
  • After mounting, for tight transition fit (keeping inner ring from rotating relative to shaft), inner-ring O.D. must not exceed raceway diameter on matching bearing.
  • After mounting, if O.D. of inner ring exceeds the required raceway diameter for matching bearing, ring should be ground to proper diameter while mounted on shaft.
  • Unmarked end of inner ring to be assembled against the shaft shoulder to ensure clearing the maximum allowable shaft fillet as indicated in tables shown.
