  Hydraulic Cylinder rods   are chrome-plated steel products that can be supplied as  piston rods   in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar.Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc. The piston rod is typically a hard chrome-plated piece of cold-rolled steel that 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 c...

  The stroke of   hydraulic cylinder   is the amount of travel the   piston rod   can move in and out. It can be found by subtracting the maximum extended length of the hydraulic cylinder from it’s minimum compressed length. Generally the compressed length is given along with the stroke. To find the maximum length of the cylinder, you have to add the two together. Stroke lengths are standardized more or less in 2″ increments from 4″ to 24″, and larger increments above those lengths, such as 6″. Another standardization is that the compressed length for cylinders of any given stroke is usually the same between cylinders. For example, most cylinders with a 12″ stroke will have a 22.25″ compressed length.

  Two methods have become established for hardening workpieces in mass production: case hardening and induction hardening. A comparison of these two methods shows their differences and the advantages of each. Case Hardening vs. Induction Hardening – a Comparison If one compares the two methods for hardening steel workpieces (for a general explanation of hardening see here: Hardening), then the first striking difference is the parts handling. While case hardening processes a large number of workpieces at the same time, induction hardening focuses on the individual workpiece. With induction hardening, components are hardened workpiece . For case hardening, “batch by batch” would be a better description. Of courses, this has an impact on the manufacturing. While case hardening relies on parts logistics to carry parts between the production line and hardening, induction hardening can be integrated directly in the production line with a suitable hardening machine (e.g. MIND series) and ...

Honed tube  widely used to manufacture  hydraulic cylinders , so it is known as hydraulic cylinder tube.This product is made from cold drawn seamless steel tube (CDS tube), by the process of honing or Skiving & Roller Burnishing (SRB for short) on the inside surface.  As one of the leading honed tube Manufacturers, all the honed cylinder tubing of our factory is offered in both metric and standard sizes and may be cut to length to meet customers’ requirements
