Hydraulic cylinder tube  is one typical application type of honed tube. It is made from  cold drawn seamless steel tube  (CDS tube), by the process of honing or Skiving & Roller Burnishing (SRB tube) on the inside surface. It is widely used to manufacture hydraulic cylinders, so it is known as hydraulic cylinder tube. As the most experienced hydraulic cylinder tube supplier and manufacturer, we can understand the requirements of our customers accurately, and we can give our suggestions to our customers to help them to choose the right materials and the hydraulic cylinder tube sizes. Here below are the main features of our hydraulic precision cylinder tubes. Tolerance  Our cylinder tubes with high accuracy tolerance can be provided by us at premium cost, mostly the tolerance of the honed tube  ID is ISO H8 ; and we also can manufacture hydraulic cylinder tubes with  ID tolerance H7 or H9  on customer’s request. Ovality  The ovality of cylinder tube is over the limitations of ID tole

42CrMo, 4140, SCM440, 42CrMo4 High Tensile Steel Bar

42CrMo is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness. This steel usually adopts quenching after tempering as the heat treatment solution. After tempering, it has relatively high fatigue and impact resistance and no obvious temper brittleness.    42CrMo has good mechanical properties and machinability, mainly in the form of plate and round rod. In the processing industry, the 42CrMo plate for the mold processing production, the 42CrMo round rod for mechanical direct processing parts. 42CrMo bar and plate is mainly used for manufacturing important structural parts working under high load such as hydraulic shafts, transmission gear, supercharger gear, engine cylinder; Spring clip, oil drill pipe clamp first class parts. In the mold manufacturing industry, 42CrMo is also suitable for large and medium-sized plastic molds with certain strength and toughness. The corresponding material of 42CrMo steel as per the European Union, Japan, Germ

Top 5 Hydraulic Cylinder Repair Tips

Image
Hydraulic cylinders  are an integral part of the hydraulic system. They are a mechanical actuator that provides the unidirectional force. Integration of hydraulic cylinders will eliminate the presence of levers and gears. Both mobile(hydraulic presses, cranes, forges, and packing machines) and industrial systems(agricultural machines, construction vehicles, marine equipment) utilize hydraulic systems. Among them, most of the application use hydraulic cylinders for lifting, picking and gripping.  Every hydraulic system will contain basic components like pumps, cylinders, valves, filters, etc.. Hydraulic cylinder is one of the least complicated components in the list. So, they are easy to repair and maintain. A person having basic knowledge about the hydraulic system can perform hydraulic cylinder repairing. Before explaining the repairing of cylinders, I will give you brief details on the causes of hydraulic cylinder failure. Damage of seals is a common reason that creates hydraulic cyl

THE WIDE APPLICATIONS OF HYDRAULIC CYLINDER

Image
Hydraulic cylinder  is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has a simple structure and reliable operation. When it is used to realize reciprocating motion, the reduction device can be eliminated, and there is no transmission gap, and the movement is stable, so it is widely used in hydraulic systems of various machines. The output force of the hydraulic cylinder is directly proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder basically consists of a  cylinder barrel  and a cylinder head, a piston and a  piston rod , a sealing device, a buffer device and an exhaust device. The buffer device and exhaust device depend on the specific application, and other devices are necessary. Datong Hydraulic  is a professional manufacturer in hydraulic cylinder and assembly products , we have more than 23 years experience,  honed tube  , hard

Requirements and material section of hydraulic cylinder barrel

Image
The required barrel is a key part of hydraulic cylinder , and sometimes the direct acting component of hydraulic cylinder (when piston rod or plunger is fixed); the barrel, end cover and piston (plunger) form a sealed chamber for containing pressure oil and driving the load for acting; thus the barrel has requirements for strength, rigidity and sealing as below: (1) The barrel should have sufficient strength to prevent permanent deformation under long-term rated operating pressure and short-term dynamic test pressure. (2) The barrel should have sufficient rigidity to prevent bending caused by lateral force imposed by the piston and reacting force during installation. (3) Reliable seal: The grade of dimensional tolerance and accuracy of geometric tolerance of cylinder inner surface, piston seal and supporting ring should be designed rationally to ensure reliable seal and reduce wear. (4) The cylinder barrel to be welded should have good weldability to avoid cracking or excess

How Does Hydraulic Cylinder Work?

Image
A  hydraulic cylinder  (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in construction equipment (engineering vehicles), manufacturing machinery, and civil engineering. Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. The hydraulic cylinder consists of a  cylinder barrel , in which a piston connected to a  piston rod  moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals. The piston divides the inside of the cylinder into two chambers, the bottom chamber (cap end) and the piston rod side chamber (rod end / head end). Flanges, trunnions, clevises, and lugs are common cylinder mounting options. The piston rod also has mounting
