The hub keyway is dimensioned by its width and depth on the shaft - keyway sides. Referencing Figure 1, the keyway dimension is W x T 1. 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 common
