Advances in Shaft Measurement
The term “shaft measurement system” is standard industry parlance today, but to think of these gages as measuring only shafts is too limiting.

If there are features such as diameters, lengths, groove widths, fillet radii or chamfers on the part then it is well suited for measurement by a shaft measurement system.
