Honed tube is well known as hydraulic cylinder tube in many industries. This is because honed tubes are the most important materials of manufacturing hydraulic cylinders. And as this kind of tubing is usually honed in tube inside diameter, it is known as honed ID tubing also.
The honed tubes suitable for various kinds of Precision Mechanical Tube, Honed Cylinder Tubing and Hydraulic Cylinder, Construct use Multi Joint Tube, Steel Axis Pipe, Injection Machine and Robotic Arm.
Seamless Honed Tubes (Steel) with a micro-finish and highly accurate in bore size within tolerance H7 or equivalent.
Grade: ST 52, ST52.3, CK45, E355, 16Mn, STKM13C, SAE1020, SAE1026, SAE1045
Hard Chrome Plated Tube Rod has same properties as normal coated rod with the chrome coating on the outer surface. It reduces your system weight 50%-60% due to the hollow design.
Honed Tubes are ready to use for hydraulic cylinder applications without further ID processing.
Type:
Different sizes of ready to use honed tube are available.
