HYDRAULIC SERVO CYLINDER Depending on the requirements in terms of accuracy, servo cylinders are used with two construction designs, which differ in terms of the bearing of the piston and piston rod. 1. Cylinder with hydrostatic bearing 2. Cylinder with contact seals, which must have a particularly low level of friction. These special seals are normally made of Teflon. Servo cylinders, together with the load, form a system capable of oscillation with a relatively low natural frequency and very low damping, between 0.05 and 0.2. Hydraulic Cylinders are offered with a complete range of fluid power products making Hydropower a "Single Source Supplier" for your complete Hydraulic requirements and thereby ensuring a SINGLE SOURCE RESPONSIBILITY. BARRELS: Hydropower hydraulic cylinder barrels are made from the imported Cold Drown Seamless Steel Pipes for reliable long life performance. SEALS: The seals are critical components of the hydraulic cylinders. Hydropower hydraulic cylinders are provided with Unique Piston Rings. For the static holding applications, special static pressure energized seals are provided, which offer positive sealing and maintenance free operation. PISTON RODS: Piston rods are made of Medium Carbon Steel and are Hard-Chrome Plated and Ground to provide a smooth, hard and scratch resistant surface for long life trouble free operation. PISTONS: One -piece, wide surface pistons of Hydropower hydraulic cylinders are made of special grade fine grained Cont. Cast Iron to withstand the heavy bearing loads, wear and impact during the operation of the cylinders. SPECIFICATIONS: 1. Cylinder Tonnage: 0.5T TO 500T. 2. Working pressure: up to 350 Bar. 3.Stroke: Up to 4000mm. 4.Type: Single acting & Double acting.
