Hydraulic balance cylinders are used in industrial robots and lifting platforms to counteract axial load torque in a closed balancing system. The official SCHWERLL product description states that enclosed gas in a diaphragm accumulator functions like a mechanical spring.
Published structural features include a double-acting hydraulic cylinder, pull or push configurations, optional low-temperature models, and alternative piston-rod surface treatments including induction-hardened hard-chrome plating and nickel-chromium plating.
The SCHWERLL product page also publishes page-level working parameters of 50β90 mm piston diameter, 28β45 mm maximum rod diameter, up to 50 mm stroke, and a maximum working pressure of 400 bar. These values are not currently mapped to SCH-1019 or to a confirmed supplied model/component and therefore must be confirmed before use as selection or rating data.
The official page describes a CE-certified complete module, but the corresponding declaration and covered model/module have not been mapped to SCH-1019. Confirm the applicable compliance documentation for the exact configuration offered.
