The RIVERLAKE HDC Series redefines hydraulic performance with its dual-circuit design, delivering unparalleled strength, precision, and durability for demanding industrial applications. • Equipped with a spherical saddle,it effectively enhances the anti-overload capability of the hydraulic cylinder • Alloy quenched and tempered steel piston, surface hard chrome plated, anti-magnetic and corrosion resistant. • Overtravel protection and return overpressure protection switch, automatic pressure relief in case of overtravel and return overpressure, provide strong safety protection. • The T-type seal structure provides a minimum of 1.3 times the full-stroke high-pressure life performance. • The hydraulic cylinder body is made of 42Crmo alloy steel. After heat treatment, the hardness is as high as HRC43, the surface roughness is Ra 0.2, and it has long life and high strength. • The dust ring prevents external impurities from entering the inner cavity of the cylinder and causing pollution and tool damage. • Composite material bearing wear rings greatly improve the supporting capacity of the piston and enhance the hydraulic cylinder’s ability to resist eccentric loads.
