According to DIN Norm:
EN 10305-1, EN 10305-2, ASTM A513, ASTM A519, stainless steel and aluminium
We supply hydraulic cylinder tubes made out of the steel grades E355 to P700mod., stainless steel 1.4301, Valima 1.4306, 1.4571, 1.4404 and other varieties for trade and industry. The tubes are processed by qualified personnel using the most modern CNC machines.
As a result of our very own manufacturing depth and process control, we have a decisive influence control of the material, the production and on the inner surfaces. Our three skiving and roller burnishing machines guarantee quality, short delivery times, flexibility and cost-effective production. We manufacture tube lengths up to 12,000 mm.
Although this makes Seidel Stahlrohr one of the largest manufacturers of hydraulic cylinder tubes in Europe, thanks to modern logistics and process automation, even small lot sizes can be supplied economically.
Our delivery program of cylinder tubes includes inner diameters from 38 to 320 mm and lengths up to maximum 12,000 mm, with ISO-tolerance H8. Surface roughness Ra maximum 0.20 µm.
Special surfaces, for example, having a specific bearing line fraction or other parameters can be manufactured.
Optional we could produce for you as a sub-contracter.
