what are hydraulic cylinder rods made of ?

  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...

What is the stroke on a hydraulic cylinder?

Image
  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.

What is the technological difference between Case Hardening and Induction Hardening

  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 ...

Top 3 hydraulic cylinder manufacturers-Datong Hydraulic

Image
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

PRODUCTION PROCESS OF CHROME PLATED HONED TUBE

  ST52 chrome plated   honed tube  is used for the production of mechanical parts. Its precision requirements are high, so it must be said that complicated process and strict inspection can be delivered, and with the continuous development of technology, the production process of honing pipe is constantly improving. perfect. In order to make the production efficiency of ST52 electroplating honing pipe high, we have adopted a new production process, which is produced by grinding and automatic grinding. Among them, automated grinding includes the use of electric or ultrasonic grinding to complete production tasks. The daily working principle of the ST52 electroplating honing pipe is mainly the pressure generated by the sand on the belt, and the surface grinding under the rotation speed. After the upper and lower movement of the abrasive belt, the upper and lower surfaces of the workpiece are grounded back and forth to achieve the effect. Of course, in the grinding process, ...

What is the bore of a hydraulic cylinder?

Image
Bore is the inner diameter of the  hydraulic cylinder . The size of the bore can calculate by checking how much force is generated. Bigger the bore size can generated large force and the small one generate less force. The Bore of the Hydraulic cylinder decides the all-out intensity of the cylinder. The bigger the drag, the more it can lift or push. On the off chance that you see or hear us discussing a "4-inch" cylinder, we are continually discussing the drag of the cylinder. The outside distance across (OD) is normally around 1/2″ bigger than the drag, yet it relies upon the divider thickness, so on the off chance that you quantified your cylinder all things considered and it quantifies 4-1/2″, you can be almost certain its a 4″ Bore cylinder. Datong Hydraulic  is a professional manufacturer in producing and designing hydraulic cylinder ,besides, we also produce  honed tubes  and  chrome plated bars , if you have any inquiry about  hydraulic cylinder tube ...

How To Ensure The Quality Of Precision Piston Rod?

  The   piston rod   can be used for hydraulic starting, the piston rod processing requirements are very high. Therefore, the quality of the hydraulic cylinder mainly depends on the quality of the piston rod, which is the connecting part supporting the work done by the piston, and most of which is used in the  cylinder . Cylinder motion actuator is a kind of moving part with high technical requirements. The quality of precision piston rod directly affects the life and reliability of the whole product. Although from the point of view of design, piston rod is not considered to be affected by radial force, but it is directly restricted by the actual structure in use, and the piston rod is inevitably affected by radial external force. The machining length of precision piston rod should increase its guiding function, increase bearing surface area, reduce wear and improve the service life of hydraulic cylinder, and the quality of hydraulic cylinder mainly depends on the qu...
