Description
Heavy duty push-pull linear motion feedthroughs allow linear displacement of heavier samples and components than conventional designs. These devices do not provide position indication. Sample or component position must be verified visually through a viewport. Sample linear position can be fixed with an integral position lock knob mounted on the actuator housing. Unlike conventional motion feedthroughs, heavy duty models employ reentrant welded bellows construction allowing the use of sturdier and larger diameter shafts. Push-pull linear motion feedthroughs provide two-position fast action motion ideal for applications including open-close or in-out motions similar to those used for in-vacuum shutters. Standard models with two-, four- and six-inch maximum travel are offered on 2-3/4" Conflat® compatible Del-Seal™ CF metal seal flanges. Special configurations, such as the three-inch version displayed in the photograph, may be quoted upon request.
