  HYDRAULIC HONED PRECISION TUBES Hydraulic honed tubes  are seamless, hot rolled and honed. They can be used for manufacturing any hydraulic cylinder. Honing is finishing method whose goal is to ensure perfect surface grade, in our case final treatment of the inner diameter of the tube. Advantage of this classic procedure is high geometrical accuracy of the shape with minimal conicity and waviness of the surface. However, after the process, they will be a large number of spiral grooves from the grinding tool. These result in greater wear and lesser lifespan of the seals, compared to the roller burnished tubes. Final surface will have roughness Ra 0,4 μm. Hydraulic Honed Tubes are made of ST52.0 (E355) material. ST52 Hydraulic Cylinder Tubes are preferred in various sizes and thickness by our clients all across the globe. SKIVED AND ROLLER BURNISHED PRECISION TUBES These tubes are cold drawn, skived and roller burnished. They can be used for manufacturing any hydraulic cylinde...

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 ...

hydraulic Honed tube  is a kind of tube that the inner hole of cold drawing tube is machined by honing head with the high speed grinding process, so that the inner hole achieves the tolerance dimension and surface roughness requirements required by us. It is widely used in  hydraulic cylinder  ,engineering machinery, metallurgical machinery, mining machinery, road construction machinery, textile machinery and other industries.

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 cyli...

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...
