Our Hydraulic Cylinder Tubes are manufactured with high precision to meet the demanding requirements of modern hydraulic systems. With excellent surface finish, tight dimensional tolerance, and high mechanical strength, these tubes are ideal for producing durable and high-performance hydraulic cylinders used in heavy industries.
As a professional supplier of precision honed tubes and hydraulic cylinder barrels, we provide products that ensure smooth piston movement, reduced seal wear, and long service life.
The internal bore is carefully honed to achieve a superior surface finish (Ra ≤ 0.4–0.8 μm), ensuring smooth piston travel and improved sealing performance.
Manufactured with strict tolerances such as H8 / H9, allowing easy machining and reliable cylinder assembly.
Available in various premium steel grades including:
E355 / ST52 / Q345B / Q355B
SAE 1026
20MnV6
4140 / 4130 alloy steel
These materials provide excellent strength, pressure resistance, and durability.
Our advanced manufacturing process ensures consistent wall thickness and high structural integrity for demanding hydraulic applications.
