Piston rods, drawbars and coupling rods

Forged piston rods, drawbars and coupling rods for hydraulic cylinders and drive connections suitable as movable parts for high stress use.

We offer superior forging quality in the following options: raw execution, pre-machined or fully machined.

Made from carefully selected materials. Our components will give you the highest reliability under high mechanical stress.

Construction features

Made from one piece: no weak spots due to welding or joining.
