Type SFM

All type "SFM" bushings are lapped, honed or ground in the I.D. and are concentric within .012mm T.I.R. to the O.D. A slip-fit clearance is provided for proper alignment when inserted into a liner. No-Counterbore bushings are standard with Acme. Please note that the length on type "SFM" bushings is measured under the head.
