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.
