The hub keyway is dimensioned by its width and depth on the shaft - keyway sides. Referencing Figure 1, the keyway dimension is W x T1. 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

Keyway Tolerance Chart Introducing an additional bushing component between hub and shaft improves the performance and convenience of keyed joints. Taper-Lock bushings are keyed hub fittings which provide three threaded Dutch keyways and two setscrews as Dutch keys, in addition to the rectangular keyway.
