Choose Right Grades and Sizes of Hydraulic Cylinder Tube
Honed tube is a type of smooth bore seamless steel tube used in manufacturing hydraulic cylinder. This Hydraulic Cylinder Tube can be produced in ST52, AISI 4130, E355, Aluminium or 304/ 316 Stainless Steel. Among all ST 52 seamless honed tube is most selling grade in India. ST 37.4, ST 52.4 and ST 52.3 Honed Tube come with 2 types of heat treatment process stress-relieved annealed and normalized. Hydraulic Honed Tube is a precision tube manufactured for Cranes, Earth Moving Machinery and Energy Applications.
Seamless Honed Tubes are supplied in various conditions such as BK, NBK, BKW, GBK, and BK+S. Hydraulic Cylinder Tube manufacturers offer these tubing with Highly Smooth Inner Surface as per Ra 0.4 micrometers. The allowable deviation of Honed Tube inner diameter is 0.03mm, and Hydraulic Cylinder Tube straightness is 0.3-1.5mm/m. Hydraulic cylinder tube manufacturers follow Cold Drawn Seamless (CDS) and Drawn Over Mandrel (DOM) method to produce Honed Tubing.
