Hydraulic cylinder

double-acting

Easy to use, basic hydraulic cylinders in SAE 4 ported designs Designed for long life in high production applications. Don't gamble with "cheap" cylinders which wear out prematurely Reduce or eliminate part distortion by providing accurate, repeatable clamping force Double Acting cylinders assure complete powered retraction for CNC controlled operations (where time is critical) or when using heavy end effectors. Single Acting cylinders should be used with small end effectors only and where retraction speed is not critical Coaxial spring design adds long life to Single Acting units Hardened chrome alloy steel pistons won't "mushroom" even when used without grippers Springs are designed to return the cylinder and contact points, not intended to pull mechanisms
