Hydraulic cylinder

The Hydraulic Cylinder is available from cold drawn seamless pipes of ST 52/ASTMA 106 Gr B and honed to 0.2 micron surface finish. The piston rod is made up of alloy steel, heat-treated, precisely ground, hard chrome plated and super finished. End cover made of steel is precisely machined. The piston seal is self-expanding with two side rings of PTFE, which ensure perfect sealing and very low friction to prevent stick slip motion of the piston. Rod seal is of double lip design to ensure perfect sealing made of polyurethane to provide friction less movement. The piston rod is supported by bronze filled PTFE guide rings, which increases the side load capacity. Tie rod, as well as welded construction cylinder is also available. Wiper seal prevents the entry of dust into the cylinder. Inspection is carried out at every stage of manufacturing to ensure proper and consistent quality. Static pressure testing at maximum working pressure is carried out on all cylinders.
