Zero Gage Co. hydraulically operated units may be actuated by outside hydraulic source or direct machine hydraulics.

Every Zero Gage Co. hydraulic arbor or chuck is cycled on test equipment designed and built by Zero Gage Co. for assurance against defects. The test instrument simulates manual or power actuating operations of the hydraulic arbor or chuck. Variable controls allow duplication of operation cycle time when checking data pertaining to materials, elastic limits, and high pressure hydraulic seals. the test equipment guarantees each unit meets the production engineer's requirements for consistently accurate functioning within the demanded tolerances.
