Heavy Duty Hydraulic Cylinders

CD_CG250, CD_CG350 series heavy-duty Hydraulic cylinders, the installation type and connection size of this product are in accordance with the standards of German steel mills and ISO3320, especially suitable for the harsh environment, heavy-duty working conditions, widely used in steel, Casting, Forging and machinery manufacturing and other industrial sectors.
Technical characteristics

• The dynamic seal adopts the v-ring group suitable for high speed and high pressure or the sliding ring combination with low friction coefficient suitable for low speed and low pressure

• The Hydraulic Cylinder is of double-acting single piston type, including differential cylinder and equal speed cylinder, with adjustable buffer (adjustable throttle valve is adopted).

Application field

Steel, casting, forging and machinery manufacturing industries such as harsh environment, heavy duty working conditions.
