CYLINDER BUSHING is made of steel with a yield point
Re> 320MPa. The technology of diamonding and finishing by rolling allows to obtain a finish with a surface roughness of at least Ra = 0.32. The range of diameters from Ø25 to Ø350, depending on the diameter, up to a length of 8 meters.
PISTON is made from steel with yield strength Re> 335MPa,and for welded structures Re> 440MPa. The surface of the piston rods is covered with chrome with a layer thickness of> 20 μm and diameters up to Ø240. Made depending on the diameter up to 8 meters. We also make piston rods from open-die forgings where the surface of the piston rod is covered with chrome with a layer thickness of 20 ÷ 30 μm and is polished to Ra = 0.32. On special orders, we make piston rods covered with a nickel-chrome protective coating.
BALL JOINTS are being produced by us and are made of steel with the yield strength Re> 800 MPa and are subjected to the nitro-sulphurization process, reducing friction of the joint elements.
BREAKING THE SPEED OF MOVEMENT OF THE PISTON in extreme positions, depending on the design of the actuator and a given series of types, is available from the piston diameter of Ø63mm or Ø80mm.
