Honed Tubes

Precision Cylinder Tubes. Micro-Finished ID (H8) for Hydraulic & Pneumatic Applications.

Manufacturing Types

Cold Drawn Seamless (CDS). Grade ST52 / E355+SR. Traditional abrasive honing for a perfect cross-hatch pattern, extending seal life.

Enquiry Specs

Advanced SRB process creates a mirror-like ID finish (Ra < 0.2µm) and induces compressive surface stress for higher durability.

Enquiry Specs

Drawn Over Mandrel (DOM) welded tubes. Grade E355+C. Offers superior concentricity and uniform wall thickness at a competitive price.
