The double-acting hydraulic cylinder stands out for its bidirectional drive capability,providing uniform force in both extension and retraction,ensuring smooth and shock-free movement.Key features include a high-strength stainless steel cylinder tube with strong corrosion resistance,suitable for humid or chemical environments;the piston rod uses hard-chrome-plated stainless steel with high surface hardness and excellent wear resistance.The sealing system employs Fluorocarbon Rubber(FKM),offering high-temperature and chemical resistance with minimal leakage,extending maintenance intervals.Trunnion mounting allows for flexible angular adjustment,facilitating integration into complex systems.The fixed cushioning design effectively absorbs energy at the stroke ends,reducing vibration and noise.Additionally,this hydraulic cylinder supports high working pressure(250 bar)and fast response(max speed 1.0 m/s),making it suitable for high-frequency cycling applications.The overall structure is optimized to be lightweight yet durable,ideal for heavy-duty industrial environments.
This double-acting hydraulic cylinder's specifications are based on ISO 6020 standards,with an 80mm bore diameter,40mm rod diameter,and a 500mm stroke(customizable up to 1000mm).The working pressure is 250 bar,with a test pressure of 315 bar,ensuring a safety margin.The maximum speed is 1.0 m/s,and the minimum starting pressure is below 5 bar,providing high-precision control.Material-wise,the cylinder tube is 304 stainless steel with a tensile strength≥500 MPa;the piston rod is 17-4PH stainless steel with a hard chrome plating thickness of 25-35µm;seals are FKM,resistant to temperatures from-30°C to 100°C;the piston uses bronze to reduce friction.It weighs approximately 12kg,features an SAE flange mounting interface,and has a G3/8 port size.With an IP67 protection rating,it is fully dust-tight and protected against temporary immersion,suitable for outdoor or harsh operating conditions.These specifications guarantee the cylinder's reliability and long service life in high-pressure,high-load applications.
Double-acting hydraulic cylinders are widely used in fields requiring precise bidirectional control.In industrial automation,they are used in feed systems for injection molding machines,presses,and machine tools to achieve high-speed reciprocating motion.The construction industry commonly uses them in excavator arms and bulldozer blade control,providing powerful push and pull forces.Marine systems employ them in steering gears and hatch operations,where the corrosion-resistant design suits the marine environment.Agricultural equipment like harvesters also use these cylinders to adjust cutterbar height.Furthermore,in the energy sector,wind turbine pitch systems rely on their high-precision movement.Their high load capacity(up to several tons)and long stroke options make them key components in heavy industries like steel manufacturing.Overall,this hydraulic cylinder is suitable for high-dynamic,high-reliability application scenarios.
