Hydraulic cylinder barrel is honed tubing made of cold drawn seamless tubes with material steel grade ST52/ST52.3. This product is broadly utilized as hydraulic cylinder body in many industries, it is used to produce and repair hydraulic cylinders and pneumatic cylinders.
 
Honed tubing for hydraulic cylinder barrel usually is produced by two main manufacturing process, which are honing process or skiving & roller burnishing process. The mother tube we usually use "Suitable To Hone" Cold Drawn Seamless Tubes. The process of the honed cylinder tubing is determined upon the dimension, mold available and the requirement of the customer.

Product Details
 
Materials:
The most popular material of our honed tube is carbon steel grade ST52 /ST52.3. And we also produce hydraulic cylinder barrel tubes in other materials such as SAE 1026, E355 and SAE1020, stainless steel and so on.
 
Size Range:
As the leading honed tube manufacturer in China, our factory produce honed cylinder tubes in a wide range of metric sizes and imperial sizes.
Inside Diameter 32mm to 600mm; Imperial sizes equally.
We supply our honed tubing in fixed length and random lengths, the max. Length our our honed tube is 14 meters.
 
Applications:
Our Hydraulic cylinder barrel is mostly applied for making and repairing hydraulic cylinders and pneumatic cylinders, this product is popularly used as hydraulic cylinder body; and our honed cylinder barrel tubing is ready to use as hydraulic cylinder tubes without any further inside diameter machining. 

Besides the above, our honed hydraulic cylinder barrel tubes also can be used in other applications where high precise inside diameter dimension is required and high smoothly inside surface is required.

As the professional hydraulic cylinder material manufacturer and supplier, besides honed tubing, our factory also produces below products for cylinder manufacturing and repairing applications.

1. Chrome plated shafts

Hard Chrome plated shafts are known as chrome plated rods or chrome plated bars also. This series product is another main product line of our factory, it is mostly used to manufacture and repair the hydraulic piston rods. Our hard chrome plated shaft are produced from steel round rod by high precise grinding, polishing, and chrome plated to a certain thickness on the external surface, the thickness of chrome plated layer is usually min. 20 microns. The material of the chrome plated shafts of our factoy can be carbon steel as CK45 (chrome bar of CK45 is known as CK45 hydraulic piston rod also), SAE 4140 (known as 4140 chrome plated bar), and stainless steel grades 304, 304L, 316, 316L. The available sizes of our chrome plated shaft is from diameter 6 mm to 800 mm, we also provide imperial sizes accordingly.

2. Chrome plated hollow bar

Chrome plated hollow bar is known as Chrome plated OD tube too, this product has the same function with chrome plated bar, but with much lighter unit weight than that. Using chrome plated hollow bar, the hydraulic cylinder weight can be greatly reduced, so the hydraulic cylinder will be more energy efficient. Our chrome plated tube is produced from seamless hollow bar, by polishing the outside surface and chrome plated to a certain thickness. Our chrome plated tubes can also be honed in inside diameter for manufacturing and repairing telescoping hydraulic cylinders.

3. Outer chrome plated and ID honed tubes

The honed ID tube with outer diameter precision ground and chrome plated is usually designed for Telescopic hydraulic cylinder. This product is actually belongs to the product line of chrome plated tube.
