What is a keyway bushing?

Keyway broaches, keyseating broaches, keyway broach shims, and keyway broach bushings are used to machine keyways, splines, and other irregular shapes into a hole in metalworking tasks.

How do you design a shaft key?

Key dimensions: Parallel keys are most commonly used. The key and key seat cross section are ISO standardized. The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion.

Which chisel is used for cutting keyways?

What is a keyway broach set used for?

Keyseating broaches are used for producing keyway-shaped holes in a workpiece. They are ground to precision keyway tolerances and designed for AF series machines. Keyway broaches are used for producing keyway-shaped holes in a workpiece. They may be used with shims if the depth cannot be broached in a single pass.

How do you dimension a keyway?

In the English system, it is standard practice to dimension keyways. 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.
