1, the Metric key size is W x T. The keyway dimensions are also different from the English system. Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway. See dimensions W and h in Figure 1. Unless otherwise specified, the shaft keyway is assumed to be standard. Also, T 1 and T 2

2022/4/12 · The keyway is a longitudinal slot in both the shaft and mating part. The keyseat in a shaft for a parallel key. A sprocket with an internal parallel keyway. Cross-section of a parallel keyed joint. W = d/4[clarification needed] H = 2d/3[clarification needed] where. W is the key width. H is the key height.

one shaft moves along its axis relative to the other shaft. (figure 3) Misalignment can result from a combination of manufacturing tolerances, poor installation practices, thermal growth or shrinkage, foundation movement, and/or component wear. The

the following tolerances for maximum lead (due to angular displacement of keyseat centerline from centerline of shaft or bore and measured at right angles to the shaft or bore centerline) of keyseats in shaft and bore are specified: 0.002 inch for keyseat length up to and including 4 inches; 0.0005 inch per inch of length for keyseat lengths
