Oil cylinder tube manufacturer spot wholesale and retail

The skiving tool is a multifunctional tool used in the manufacturing of hydraulic cylinders. Skiving is operated like this: Two thin chips are cut at a high feed rate (1-4 mm/rev) while the tool passes through the work piece. This cutting operation determines the finished diameter and tolerance of the hydraulic tube. Surface finish Ra= 4-10 μm (skiving)

Products Details

Shandong jute Pipe Industry Co., Ltd. have established in 1992. Main products as follows: 1. Hydraulic Cylinder Tube——Main products of Jute, Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder. 2. Honed tube —– used in Elevator buffer and Hydraulic Cylinder .This kind tube have a better roughness inner the tube,ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M. 3. Cold finished tube—- Widely Used. Processing range 30-300mm, biggest length is 11M.
