Material 42CrMo4 QT Induction Hardened Piston Rod

 The induction hardened piston rod is typically a hard chrome-plated piece of cold-rolled steel which attaches to the piston and extends from the cylinder through the rod-end head. In double rod-end cylinders, the actuator has a rod extending from both sides of the piston and out both ends of the barrel. The piston rod connects the hydraulic actuator to the machine component doing the work. This connection can be in the form of a machine thread or a mounting attachment. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage.

Induction hardened is a form of heat treatment in which a metal part is heated by induction heating. Induction hardened piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them. The hardness after this heat treatment is HRC 40 to 45.



External Diameter Tolerance: Our chrome plated bars are supplied with tolerance f7, f8, f9 on customers’ request.
Hard Chrome Plated Thickness: Min. 20Microns (0.0008″), other chrome plated thickness of hydraulic cylinder rod is on customers’ requests. The chrome plated round bar should pass the salt spray tested at least 48 hours.
Supply Length: Our factory produce chrome plated rod with random length or fixed length up to 16 meters.

We are rich experience manufacturers of chromed bar (cylinder rods) and honed tube in china.We want to be sure that the material we sell are the best grade.

How to deal with the scratch on the surface of hydraulic cylinder barrel

Image
As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 1.First,  to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove. Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel. 2. We usually use special  repairing adhesive  to solve the scratches on the surface of  hydraulic cylinder barrel ...

Heat Treatments Of Seamless Steel Tube

Image
Heat treatment of  seamless steel tubes  is a process to improve the properties of metal materials and their products. Depending on the use, the material and its workpiece are heated to the appropriate temperature, insulated, and then cooled in different ways to alter the internal structure to achieve the desired performance. Heat treatment of seamless steel tubes is generally divided into annealing, normalizing, quenching, tempering, failure, chemical heat treatment and vacuum heat treatment. By heat treatment, the efficiency or life of the steel can be improved, and in some cases, more expensive special materials can be used instead of cheaper ordinary metal materials. The basic heat treatment methods of seamless steel tubes mainly include the following four forms: 1. Annealing Annealing is a process in which a seamless steel tube is heated to a slightly higher or lower critical temperature for a period of time (ie, heat preservation) and then slowly cooled. Common annealing...

HOW TO REPAIR THE HYDRAULIC CYLINDER ROD

  Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue. COMMON POINTS OF HYDRAULIC CYLINDER FAILURE There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod , seals, and head. PISTON The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydra...
