Hydraulic cylinder for medium and large excavators

Series advantages

•Compact structural design, high-strength material use, and special heat treatment and welding processes ensure that the oil  cylinder has extremely high fatigue durability life under high pressure and heavy load

• Designed with a wide temperature resistance range (-25 ℃~+120 ℃), and able to provide customized oil cylinder services for higher or lower temperatures

• Provide various surface anti-corrosion treatment solutions: Ni/Cr electroplating, ceramic spraying, laser cladding QPQ、 Galvanized nickel, etc

• Can design and integrate hydraulic locks, explosion-proof valves, oil pipes, etc. according to requirements

•The mature buffer design reduces the impact of the hydraulic cylinder on the bucket during excavation operations without reducing excavation force or affecting work efficiency

•Earrings for integral forged parts can be equipped with standard self-lubricating shaft sleeves or configured according to customer needs

•According to customer needs, large diameter dual oil ports can be selected and pressure testing points can be added for real-time monitoring

• Adding a buffering adjustment valve core can adjust the buffering effect in real time according to the operating experience

•Optimize the design at the points where the oil cylinder is prone to failure, reduce stress, and use special processes to ensure the reliability and stability of the oil cylinder

•Work pressure, size specifications, installation methods, etc. can be customized according to customer needs for design
