Medium carbon steel forging of the chuck body ensures ductility, strength and good wear resistance; It is hardened and tempered to ensure long life and strength to the chuck body. Precision grinding of the base jaw slots in the body ensures close tolerances for obtaining a good sliding fit. Also, this results in a play free functioning, high load carrying capacity and maximum wear resistance.

GMT system of independent four jaw chucks has separate jaws and reversible hard jaws. This gives the flexibility to use special hard jaws to suit specific component. The hard jaws connects to the base jaws by tongue and tenon. As a result. they can grip a wide range of components, either on their OD or ID.

Base jaws are made of alloy steel. Furthermore, case-hardening provides adequate wear resistance on the surface. It is deeper and wider for providing large bearing areas which reduces unit bearing pressure, thereby increasing the life of the chuck. Square threads cut on the screws and on the underside of the base jaws have longer mesh with each other, which results in efficient transmission and conversion of applied torque. As a result of heat treating the screws,  we prevent breakage, a common complaint in the commercial quality chucks. Download technical data.
