High-Precision Hydraulic Cylinder Tube Manufacturer

Hydraulic Cylinder tube is a kind of precision tube finally used for construction of hydraulic cylinder barrel. The key quality index is internal surface quality, including ID tolerance&ovality, internal surface roughness, etc. Others are determined by design.

Hydraulic Cylinder Tubes

Precision-engineered seamless or welded steel tubes used for cylinder barrels, available honed or skived for ultra-smooth internal finishes.

Honed Steel Tubes

Cold drawn seamless steel tubes honed to tight tolerances (H8/H9) with Ra ≤ 0.25μm, ideal for industrial cylinders and fluid power systems.

Hydraulic Cylinder Steel Pipes

Used in medium to high-pressure applications, available in ST52, E355, SAE 1026, and alloy grades such as 4140 and 25CrMo4.

High Precision Hydraulic Cylinder Tube Manufacturing Line

Our Advantages:

• Regular stock of quality raw material from leading mills. Fine melting of raw material ensures the purity of steel, hence surface perfection after ID deep hole boring, honing or skiving&roller burnishing.

• Advanced skiving&roller burnishing machine up to 9 meters. This ensures consistent internal surface, ID tolerance, as well as bore roughness. Automatic blade sawing machine that ensures cut squareness within 0.5mm.

• Automatic blade sawing machine controls the cut squareness within 0.5mm.

• Value added service like OD polishing is available.

• Customized services like OD machining or CNC turning are available.

Frequently Asked Questions (FAQ)

Q1: What are your standard hydraulic cylinder tube sizes?

A: ID from 40 mm to 580 mm, wall thickness up to 35 mm. Special sizes available on request.

Q2: Do you supply hydraulic cylinder parts as well?

A: Yes, we provide complete cylinder kits including rods, pistons, and machined end caps.

Q3: What is the advantage of honed tubes vs. skived & roller burnished?

A: Honed tubes offer excellent surface smoothness, while skived & roller burnished tubes provide better wear resistance.

Q4: Can I get material certificates and test reports?

A: Yes, all tubes come with EN10204 3.1 certificates and inspection reports.

Q5: Do you maintain inventory for urgent orders?

A: Yes, we keep stock of standard hydraulic cylinder tube sizes for fast dispatch.
