Reliable Honed Tube Supplier with 1mm per Meter Straightness
As a trusted honed tube supplier, we specialize in delivering precision ST52 honed cylinder tubes designed for hydraulic and pneumatic applications. Our seamless steel pipe are manufactured from high-quality materials such as EN 1.0580, E355, JIS STKM13C, DIN ST52, and SAE1020 to ensure outstanding mechanical strength, dimensional stability, and long-lasting performance.
Each ST52 honed cylinder tube features excellent internal diameter accuracy (available in H7, H8, and H9 tolerances), paired with a superior surface finish of Ra 0.2μm to minimize friction and wear in demanding environments. With straightness controlled to 1–1.2mm per meter and roundness tolerance × 1/2, these ST52 honed cylinder tubes guarantee smooth motion and stable pressure transmission in hydraulic cylinders.
We offer a wide size range with internal diameters from 18Ø to 400Ø, standard lengths from 3M to 12M, and extended lengths up to 13M upon request. For large-diameter or special projects, custom ST52 honed cylinder tube can be provided with internal diameters up to 1000mm and buffing lengths up to 13000mm.
Our ST52 honed cylinder tubes are widely used in construction equipment, automotive systems, and heavy-duty industrial machinery. With strict quality control and advanced manufacturing, we deliver honed tubes that meet the most demanding standards for accuracy, strength, and durability.
If you're looking for high-precision honed ID tubing made from durable materials for demanding industrial applications, our seamless steel pipe solutions are the ideal choice. Manufactured from EN 1.0580, E355, JIS STKM13C, DIN ST52, and SAE1020 carbon steel, these cold drawn or skived and roller-burnished tubes deliver superior mechanical strength, excellent internal surface finish, and long service life.
Our seamless steel pipe with honed inner diameter is specifically designed for hydraulic and pneumatic systems that require tight tolerances, high durability, and minimal maintenance. The smooth internal surface reduces friction and wear, promoting efficient pressure transmission and extending the life of internal components.
These honed ID tubing products are produced according to strict quality standards and are widely used across industries such as mining, construction, automotive, and automation. With high resistance to fatigue and compression, they help reduce system downtime and improve operational stability.
Key Benefits:
- Durability and Resistance: Carbon seamless steel pipe base material ensures long-lasting performance, even under high pressure and stress.
- High Precision and Efficiency: Honed ID finish enables stable and accurate hydraulic function.
- Friction Reduction: Smooth internal walls minimize component wear and energy loss.
- Versatile Applications: Suitable for a wide range of industrial uses requiring high reliability and pressure control.
Whether you need customized specifications or standard sizes, our seamless steel pipe and honed ID tubing offer the reliability and performance your hydraulic systems demand.
