Sleeves are typical of the complex, tight tolerance parts produced by Worthington Precision Metals in high volumes.

The internal slotting, heat treatment and internal diamond sizing processes used produce sleeves which do not need to be "matched" to the mating input shaft.

Tolerances Held:
Internal Diameter: 5.0 microns
Roundness and taper: 3.8 microns
Slot location using specialty CNC slotting equipment
