With Jaw Force Gauges, users can accurately measure force applied to each chuck jaw independently, so that problems can be diagnosed and corrected before failure occurs. Reading in pounds of chucking force per jaw is holding force available for that specific jaw. Providing force range from 0–30,000 lb, gauges are suitable for chucks from 6–18 in. Gauges identify potential safety hazards and keep chucks operating at full force for maximum production and service life.
