Follow any specific recommendations for rounding on the Routing sheet with the order. If no specific instructions are seen, +/- 0.031" (1/32") is the maximum allowable variation from the sleeve OD listed on the work order cover sheet. The following tolerances are recommended as a refinement for specific types of seals.

 

Tolerances for the Sleeve OD listed on the work order cover sheet:

OD lip seals:      +0.020" / -0.010"

ID lip seals:        +0.010" / -0.020"

Square Rings:     +0.030" / -0.030"

 

Instructions for Rounding a Sleeve:

  1. Choose a mold equal to the required outside diameter of the sleeve or a pin equal to the required inside diameter of the sleeve.
  2. Place the sleeve to be rounded in the small oven at 690oF for approximately one (1) minute.
  3. Remove the sleeve from the oven using fire safe gloves.
  4. Slide or push the sleeve through or over the mold or pin.
  5. Allow the sleeve to cool and remove the sleeve form the mold or pin.
  6. Stack the parts in the machining area and stacked by sleeve size.
  7. One sleeve per stack should have the part number on it and the work order should be placed with the stack
