Chuck Actuators

LMC Workholding offers two chuck actuators specifically designed for wheel chuck applications like yours. These hydraulic cylinders offer optimum hydraulic system pressure settings for the fastest clamping/unclamping action available. Their shorter lengths and lighter weights enhance lathe acceleration and deceleration while improving machine dynamics and reducing energy consumption. Model LWC1120 is a single-motion cylinder ideal for applications that use solid mandrels or spring rings for wheel centering. Model LWC2146 is a dual motion cylinder that is ideal for applications that actuate a collet or the LMC Active Centering System.
