About HSZ Zylinderbau GmbH
HSZ Zylinderbau GmbH, based in Plettenberg, was founded in 2003 and specializes in the manufacture, repair and distribution of hydraulic and pneumatic cylinders as well as machine and hydraulic components. The company manufactures to customer drawings or its own designs – from constructive optimization of existing components and prototype construction through to one-off production and small series. The product range includes differential, telescopic, block, plunger, parallel-motion, hollow-piston and pneumatic cylinders, as well as a stock standard differential cylinder in modular design according to DIN ISO 3320. In addition to cylinder manufacturing, HSZ offers contract machining on conventional lathes and CNC turning-milling machines, welding using various methods, and the assembly of subassemblies. Expedited repairs of all common cylinder brands to counter downtime, supplemented by spare-part, seal and raw-material inventories, round out the service portfolio. Production takes place at the head office at Am Wasserwerk 9a as well as in a separate hall for contract parts and cylinder components.
