Concentricity Gauges
Concentricity Gauges are used to assist in assuring that certain diameters are concentric or a face is square to the spline pitch diameter. Western Pegasus manufactures concentricity gauges to the same tolerance of profiling, spacing, and runout as those applied to our composite gauges.
The Concentricity Gauge is a segmented design of three splined rings, with two outer rings fixed and the central ring rotating to lock onto the component. To obtain a quantitative value, a dial gauge is set onto the concentricity band of the ring, and the component rotated.

“Being a sales representative presents itself with many challenges. In representing Western Pegasus, I never have to worry about quality, service issues, or broken promises. It is a pleasure to represent a company that serves its customers with such a high level of integrity.”
