Double Acting, Push/Pull Block Cylinder

Power Workholding

Product Information

KOSMEK Double Acting Block Cylinders are compact, linear cylinders designed for simple integration into fixture assemblies. The block-style body provides a rigid, space-efficient package that mounts directly to fixture plates and subplates. Double-acting operation provides powered motion in both directions, generating both push and pull force through a single cylinder. The powered return eliminates the spring-return mechanism found in single-acting cylinders, resulting in more robust cycle life and consistent force output in both stroke directions. This makes Block Cylinders suitable for activating linkages, core pulls, manual clamps, edge locators, and other fixture mechanisms requiring reliable linear motion. Operating pressure ranges from 10 to 350 Bar, providing broad flexibility across low-pressure and high-pressure hydraulic systems. Two mounting configurations are available: bolt-up (Model DBA) and side mount (Model DBC). Both models accept manifold mounting or direct pipe connection.

Block Cylinders are stocked in four body sizes with 25 mm stroke in both bolt-up and side mount configurations. At 350 Bar, push forces range from 17.2 to 68.5 kN and pull forces from 10.2 to 40.6 kN. Additional stroke lengths and configurations are available. Made in Japan.
