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.

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

12/15 · The second is a P9 tolerance. This is an undersized clearance. The advantage of the Js9 tolerance is that the key can be inserted and the gear manipulated without much difficulty. Whereas the P9 tolerance is a press fit tolerance. Once the key is inserted into the keyway, it is not going to move. For those engineers who wish to put a square peg

Keyways will be furnished per ISO/R773 and Js9 width tolerance unless otherwise specified. (Dimensions comply with DIN 6885/1) †Requires the use of chamfered keys.

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
