1.Description: Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder. Honed tubes are widely used in hydraulic cylinders, cylinders, hydraulic machinery, engineering machinery, petroleum machinery, agricultural machinery, filling machinery, mining machinery and other fields.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder.
Difference between honed tube and skived & roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness.
2.Commodity: Cold drawn seamless honed tube for hydraulic cylinder
3.Size range: 40mm*30mm-580mm*500mm
