  • Same as Headless Press Fit but with head (or shoulder) on the drill entry end
  • Head prevents heavy axial loads from forcing bushing through jig hole
  • Flush mounting is possible by counterboring jig hole to fit bushing head
  • Available with finish ground O.D. or unground for custom grinding

All press fit bushings are lapped, honed, or ground in the I.D. Bushings with I.D.’s of 1/8″ to 1″ are concentric within .0003″ T.I.R. to the O.D. Other I.D. sizes are held within .0005″ T.I.R.

Metric bushings are concentric within .012 T.I.R. to the O.D.

.

No Counterbore
