CHUCKS 482 All chucks are priced on application. 3-Jaw High Speed Power Chucks High quality, Lever Style, High Speed Power Chuck Cushman thru-hole high speed chucks, hydraulic cylinders and tooling are integrated, power operated workholding packages. Acme serrated master jaws are standard on these thru-hole cylinder and chuck combinations. With a work clearance hole through both hydraulic cylinder and chuck, a Cushman high speed workholding package affords great flexibility for users of conventional bar and chucking machines as well as automatic N/C equipment. Cushman high speed chucks counter centrifugal force using a system of counter weights to reduce the tendency of the jaws to release at higher speeds. NOTE: Master Jaws, Levers, Lever Pins, Plungers, Bushings, and Counterweights are available from stock upon request. Recommended Operating Limits Model No. Size (Inches) Est. Gross Wgt.

Variations in jaw force due to changes in chuck, lubrication or both may occur. Jaw force may increase with use.This will not be detrimental to the chuck as long as the increase does not exceed 20%. High-Speed Thru-Hole Chucks Series Y10-590 (2) Maximum recommended speeds are based on 50% jaw force retention at the stated WR (weight x radius to cen- ter-of-gravity) value. Specific applications must be reviewed by the user to establish that the jaw force is adequate for the loads to be encountered. Higher speeds may be permissible but must be reviewed.
