What the producing process of Honed Barrel

 Hydraulic cylinder barrels endure conditions of extreme pressure. To make them resistant to the extreme conditions under which they operate, the inside diameter of the barrel is honed to a smooth surface finish, ensuring that the barrel is free from ovality and that the bore is parallel.

The smooth surface protects the piston seals during operation, extending the effective life of the cylinder. The combination of experienced re-conditioners and high-quality machines, ensure that our clients receive the best reconditioned cylinder rods and honed barrels .

HONED BARRELS PROCESS

  1. We will source the materials E355 DIN2391 ST52 Or others, machine the different components and drill the port holes into the honed tube or hollow bar.
  2. The different components are then welded onto the tube at our factory.
  3. The semi-finished hydraulic cylinder barrel is given a final hone.
  4. Then we will package and deliver the honed barrel to your door.

Advantages of Our Honed Steel tube And Roller Burnished Steel Tube

1.High precision tolerances;

Our honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

2.Seamless tube with high pressure resistance;We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

3.High Smooth inside surface;

The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish).

Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.

4.Good weld ability: The weld ability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.

Application of 4140 chrome bar

Image
4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties, plus good machinability. 4140 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. Typical applications are: Agricultural Equipment, Hydraulic Cylinders , Hoists, Jacks and other Lifting equipment, Machine Tools, Mining and Earth Moving Equipment, Pumps, Valves, Waste Disposal Transport and Equipment etc. Anbao Hydraulic is a professional manufacturer in

The Production Process Of Chrome Plated OD Tubing

  Chrome plated od tubing is also known as chrome plated hollow bar ,chrome plated tubing a very important part for producing hydraulic piston rods and roller shafts in various machines. The biggest advantage of chrome plated od tubing than normal chrome plated rod is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the hydraulic cylinders . The Production Process Of Chrome Plated OD Tubing Step 1. Get the steel tubes heat treated as per customers’ request. Step 2. Cutting the raw material hollow rod into lengths Step 3. Straightening the hollow rods Step 4. Peeling on the steel hollow rods Step 5. Straightenning Step 6. Grinding the steel hollow rods Step 7. Straightening the ground hollow bars. Step 8. The second grinding process Step 9. Polishing on outer diameter surface Step 10. Chrome plating Step 11. Final polishing Step 12. Final inspection Anbao Hydrualic is a professional  chrome plated ID tubing and hollow bar m
