Features of H9 Hydraulic Cylinder Steel Honed Tube

Wear-resistant: The H9 Hydraulic Cylinder Steel Honed Tube is made of ST52 and Q345B high-strength alloy steel, which is twice as wear-resistant as ordinary steel pipes, and has a service life of more than 5 years.

Precision Machining: The inner diameter is precision honed, Ra≤0.4μm, tolerance±0.02mm, ensuring smooth sliding of the hydraulic piston and reducing seal wear.

Corrosion Resistance: Surface chemical nickel treatment or hard chrome plating effectively waterproofs, oil-proofs, and resists acids and alkalis.
