Hydra-Lock Corporation, Mt. Clemens, Michigan, originated, developed, and patented the concept of hydraulically expanding arbors and chucks. Although Hydra-Lock has licensed other companies to build certain patented items, today we are the ONLY MANUFACTURER who produces all three classes of this sophisticated, precision work-holding device.
Hydra-Lock arbors and chucks are designed to facilitate all types of precision gear processing. We have the ability to hold and precision locate on the pitch diameter of all types of spline and gear forms. Improve quality and cut costs by using super-accurate Hydra-Lock arbors and chucks to hold parts and tools used in hobbing, shaping, shaving, grinding and inspection operations.
Fifty years of continuous research and development have resulted in Hydra-Lock’s unmatched expertise in the production of sophisticated, precision workholding devices. Our engineers welcome “specials”, particularly the most demanding, which provide a motivating challenge for us!
