Who we are
ZS are specialized in the fabrication of special cylinders which are designed to match customers’ needs. Besides some smaller cylinders these are mainly cylinders with piston diameters between 250 and 1000 mm. Building new cylinders and repairing more than 50.000 hydraulic cylinders for coal mining and other industries have created a big potential of technical know-how in ZS. As an expert in fabrication of cylinders ZS have a lot of experience with sealing systems, scrapers, guiding systems, vibration, fluctuating pressure or corrosion.
ZS always try to find out the exact environmental conditions of the customer application, to then do the design work and fabrication accordingly. This approach often leads to new solutions, saving time and money for the customer.
