Product Features
Honed tube Ground Bore Steel Tubes are precision machined and ground to meet the stringent requirements of high accuracy, performance and reliability in hydraulic systems.honed tubes are ideal for application that requires a tube with a polished surface to the millimeter, specially for the manufacture of high pressure hydraulic cylinders.
Honed tube have two measures, millimeter and inches.
Honed tubes are manufactured to meet specific technical specifications, including:
Material: honed tube common materials include carbon steel grades such as ST52,AISI 1020, and alloy steels like AISI 4140 and 42CrMo.
Size Range: Honed tubes are available in a wide range of sizes, with inner diameters ranging from 20mm to 1000mm and lengths up to 12 meters.
Tolerance Standards: honed tube International tolerance standards such as DIN2391, EN10305, and ASTM A519 are followed to ensure global quality benchmarks.
Surface Roughness: Honed tubes feature a surface roughness between 0.2-0.4 um, suitable for applications requiring smooth surfaces.
Internal Tolerance Grades: honed tube Internal tolerance grades of H8, and H9 are achievable, meeting the precise fitting requirements of various machinery and equipment.
