| Seamless Steel Hydraulic Tube / Hydraulic Cylinder Honed Tube Hydraulic Cylinder Tube is made of JIS STKM13C/ DIN ST52/ ASTM A106/ SAE1020 and welded pipe: DIN ST52 are also offered. Seamless Steel Hydraulic Cylinder Honed Tube withstands higher pressure than welded tube without splits. But, roundness of welded honed barrels is superior to seamless pipe. After honing, carbon steel cylinder honed tube of mechanical structure use has precision diameter, smooth surface, and excellent performance of oil storage. This kind of Hydraulic Cylinder Tube and Pneumatic Cylinder Tube work smoothly without pauses and has longer working life in cylinders. Applies to hydraulic cylinders tube, pneumatic cylinders tube, forklift, crane, excavator, punching machine, and other kinds of labor-saving automatic mechanical engineering.

With the honing process, Anbao can provide honed steel tubing with an accurate tolerance of ID size up to 0.021mm (H7), with a surface roughness better (smoother) than Ra 0.8um. 2.2) SRB (Skiving Roller Burnished): The process of Skiving Roller Burnished (SRB for short) is a single step that uses a Skiving tool on the forward stroke to skive the tube ID to the desired size, and uses roller bearings on the reverse stroke, to burnish the surface to the required roughness. The SRB process is faster than honing and usually can produce more precise tolerances and smoother surface finish than honing. Using the SRB process, Anbao can supply honed steel tubing (seamless skived tubes) with ID dimension tolerance as precise as 0.021mm (H7), and smoother inner surface roughness than Ra 0.4um Generally, hydraulic cyliner tubes and pneumatic cylinder tubing produced by the above two processing are both called Steel Honed Cylinder Tubing. SRB tube is a kind of honed tube. To choose which processing method, it depends on customers' preference and the ID of the cylinder tube. 3) Size range Anbao's tube factory produces honed steel tubes in below size range. Inside diameter: 32 mm to 500 mm Wall thickness: 4 mm to 32 mm. Length: we can supply honed tubes in fixed length up to 12000 mm. 4) Materials The most popular steel grades of honed cylinder tubing is SAE 1020, we also supplier honed tubes in SAE 1026, St 52 and other steel grades such as St35, ST 52.4, St 37.4, E255, E215, etc. on customers' request. Besides carbon steel honed tubing, our factory also manufactures and supplies stainless steel honed tubing with material 316 /316L stainless steel, 304L /304 stainless steel. 5) Features As one of the main China hone tube manufacturer and supplier, honed steel tubes produced in Anbao's factory have features as below. - Smooth inside surface, the inside surface roughness could be better than Ra 0.4um. - High precision tolerance, the tolerance of honed steel tubing ID could be H7, H8, H9 accordidng to customers request. - Durable in use, as the first class quality honed tube manufacturer, our factory only uses prime quality raw materials, which insures the honed cylinder tubes durable in use. 6) Application Honed tubes and SRB tubes (skived and roller burnished tubes) are mainly used for hydraulic cylinder and pneumatic cylinder manufacturing, and in shock bodies, accumulators, motor housing, pump barrel or any other applications where precision tolerances and smooth surface finishes are required.Hydraulic Cylinder Tube factory website:http://www.cylinderbarrel.com/hydraulic-cylinder-tube/ |
