standard shaft diameter chart

This PA Note will explain the uses of keys and keyways in pulleys and bushings, and present current industry standards for key and keyway component sizing. What 

Unless otherwise specified, the shaft keyway is assumed to be standard. A list of standard keyway and corresponding key sizes for English shafts are listed below in Table 1. The
