Product Description

E355 Skived and Rolled Tube: A High-Performance Solution for Hydraulic Cylinders

E355 Skived and Rolled Tube is made from high-strength, low-alloy E355 (St52) steel and processed through skiving and roller burnishing, resulting in a smooth inner surface and tight dimensional tolerance. This manufacturing process improves straightness, hardness, and internal finish, making the tube ideal for hydraulic systems requiring consistent and reliable performance.

These tubes are often referred to as Skived Burnishied Tube, Skived and Roller Burnished Tube, or Finished Bore Tube, reflecting their high surface quality and application-ready finish. The inner diameter typically meets ISO H8 tolerance, while the surface roughness reaches Ra ≤ 0.4 μm, ensuring minimal wear on piston seals and smooth operation.

Advantages of E355 Skived and Roller Burnished Tube

Exceptional Surface Finish

With a honed-like or better-than-honed finish, the inner bore minimizes seal friction and wear. This means less downtime and longer component life.

Ready-to-Use Bore

As a Finished Bore Tube, no additional honing is needed before assembly, reducing machining time and cost.

High Dimensional Accuracy

Skiving and rolling achieve excellent concentricity and roundness, allowing seamless integration in precision hydraulic cylinders.

Enhanced Mechanical Properties

E355 steel offers high strength with good elongation, making it suitable for dynamic and heavy-duty hydraulic applications.
