   Sizing operations can assure ± .001" tolerance on disc diameters of 1.000" or less, and ± .003" on disc diameters of 1.001" or more. However, close tolerances should be avoided if possible because they result in higher costs.
   Consult our plant for maximum and minimum recommended interference for press-fit assemblies.
   Certain part designs or choice of material grade may require deviation from guideline tolerances listed above.

  

   To assure prompt handling of requests for quotations, review the checklist of items below and include all applicable items in your quotation requests:
(1) Print of part, complete with dimensional tolerances.
(2) Grade of material or micron porosity desired.
(3) Ordering quantities.
(4) Annual requirements.
