Rotary Power Chuck Introduction

It used to be complex for users to convert a manual chuck system to a power one, since setting up a hydraulic system not only is expensive, but also is troublesome. JATO Rotary Power Collet Chuck is specially designed to help users to set up a power workholding system in a low cost way. With a built-in rotary cylinder, JATO's Rotary Power Chuck allows users to easily and quickly set up a power workholding system, and saving cost on purchasing an additional rotary actuator. JATO Rotary Power Chuck also has quick-change jaw/collet design, helping you to cope with parts of various dimensions.

Rotary Power Chuck comes with both pneumatic collet chuck and hydraulic collet chuck models. Rotary Power Chuck now is widely applied to convert manual lathe to semi-auto ones with power workholding system, or is applied to build special purpose machines for machining tubes, bars, bicycle parts, etc..
