Cylinder Barrel Blanks are pre-machined seamless tubes with the bore already honed or skived & roller burnished. Cut to exact length and ready for final machining, they eliminate in-house bore finishing and shorten production cycles. Available in carbon, alloy, and stainless steel, with various heat treatments. ID up to 3000 mm, straightness ≤0.3 mm/m, bore roughness Ra ≤0.2 μm. Standard tolerances H7/H8. Ideal for streamlining hydraulic cylinder manufacturing. Custom dimensions, end preparations, and packaging offered.

Nickel or zinc-plated precision tube with a honed inner bore (Ra ≤0.2 μm, H7/H8). External plating provides targeted corrosion protection — nickel for enhanced resistance and finish, zinc for economical sacrificial protection. Base tube materials include carbon, alloy, and stainless steel, available in various heat-treated conditions. Plating thickness is fully customizable to application needs. Ideal for hydraulic cylinders in moderately corrosive or general industrial environments. Custom sizes, tolerances, and end finishes available on request.

Chrome-plated honed tube for hydraulic cylinder barrels, combining a precision-honed bore (Ra ≤0.2 μm, H7/H8) with a hard chrome-plated exterior. Chrome layer thickness standard 20–40 μm (customizable to >100 μm), hardness 850–1150 HV, and 96-hour salt spray rating 9 per ISO 10289. Base tube materials include carbon, alloy, and stainless steel in various heat-treated conditions. Offers excellent internal sealing and external corrosion resistance. Ideal for marine, offshore, and heavy-duty cylinders. Custom dimensions and tests available.

Skived & Roller Burnished (SRB) precision tube with ID up to 3000 mm, straightness ≤0.2 mm/m, and inner surface roughness Ra 0.1–0.2 μm. Manufactured in a single-pass process that combines skiving and burnishing for superior efficiency. The burnished bore features a work-hardened surface with enhanced wear resistance. Available in carbon, alloy, and stainless steel grades with various heat treatments. Ideal for long-stroke hydraulic cylinders requiring high precision and cost-effective production. Custom dimensions and finishes on request.

Precision honed tube with ID up to 3000 mm, achieving straightness ≤0.3 mm/m and inner surface roughness Ra ≤0.2 μm. Standard ID tolerances H7/H8, with H6 available on request. Base tubes in carbon, alloy, or stainless steel, offered in various heat treatment conditions. External surface finishes include zinc and nickel plating. Ideal for high-performance hydraulic cylinders, ensuring low friction and long seal life. Custom sizes, tolerances, and packaging offered.

Cold-drawn precision seamless tube with inner diameter up to 3000 mm and straightness ≤0.5 mm/m. Offering IT7–IT10 tolerances, ID to H7–H10, and inner surface roughness Ra ≤0.4 μm. Available in carbon, alloy, and stainless steels with flexible heat treatment and surface finishing options. Ideal for hydraulic cylinder barrels and precision machinery. Custom dimensions, tolerances, and packaging on request.
