Tube For Hydraulic Cylinder / Skived and roller burnished precision tubes
These tubes are cold drawn, skived and roller burnished. They can be used for manufacturing any hydraulic cylinder.
Skiving and roller burnishing is finishing method that does not remove the material in the form of chips, but rather transforms the surface layer. We will not achieve such accuracy in the geometry of the workpiece compared to honing, but it is more advantageous in terms of surface quality. Final surface will have no spiral grooves and roughness Ra 0,2.
Hydraulic Cylinder Tubes are made of ST52.3 BK+S (E355SR) material - similar to 11523 steel according to 膶SN - low-carbon steel grade with guaranteed weldability. Tubes in this design are permanently in stock in a wide assortment.
Parameters
Tensile strength Rm = min. 590 N/mm2
Yield stregth Rp0,2 = min. 450 N/mm2
Inner diameter tolerance H8
Inner diameter roughness Ra 0,2
Inner diameter straightness 1/1000 mm
Production lengths 6 - 9 m
Honed precision tubes
These tubes are seamless, hot rolled and honed. They can be used for manufacturing any hydraulic cylinder.
Honing is finishing method whose goal is to ensure perfect surface grade, in our case final treatment of the inner diameter of the tube. Advantage of this classic procedure is high geometrical accuracy of the shape with minimal conicity and waviness of the surface. However, after the process, ther will be a large number of spiral grooves from the grinding tool. These result in greater wear and lesser lifespan of the seals, compared to the roller burnished tubes. Final surface will have roughness Ra 0,4 渭m.
Tubes are made of ST52.0 (E355) material - similar to 11523 steel according to 膶SN. These tubes are not usually in stock, we will send you current price and time offer upon request.

Characteristics of materials
1. Seamless cold drawn tubes according to DIN2391 (EN10305-1) Material ST52.3 BK + S (E355SR) - similar to 膶SN 11523, low carbon grade steel, weldability guaranteed. Pipes in this design are kept permanently in stock very wide assortment. They are the most common and most used.
2. Seamless tubes, hot rolled according to DIN2448 (EN10210) Material ST52.0 (E355) - similar to 膶SN 11523, low carbon steel grade, weldability guaranteed. It is used for atypical dimensions, eventually for thick pipes wall thickness or for pipes that are outside the basic line of hydraulic pipes.
3. Pipe welded, according to DIN2393 (EN10305-2) Material ST52.3 BK + S (E355SR) - similar to 膶SN 11523, low carbon steel grade,weldability guaranteed. The dimensional range starts at an inner diameter of 40mm and ends at 125mm with a maximum wall thickness of 10mm.
