Cylinder tube
According to the cylinder pressure and inside diameter size, different steel tube would be selected.
ID ≤300mm, choose cold rolled precision seamless tube
300mm≤ID ≤500mm, choose hot rolled seamless tube
500mm≤ID ≤1000mm, choose forged tube
Steel grade : ST52,SAE1020, SAE1045,SAE1518,SAE4140,SAE4145, 27SiMn , S355JR, S355J2G3, St52-3, SUS304, SUS316L etc.
Inside boring and honing , roughness R0.2-R0.3
Inside chromed : if necessary ,tube inside chrome plating could be applied
Piston rod
steel grade : SAE4140 SAE1045,SAE4145,SAE1518, 42CrMo4, SUS410 ,SUS420, SUS304, SUS316L
Eternal company ensure that every piece piston rod would be surface hardened before plating, surface hardness is HRC55~60 , plating film thickness is 0.03~0.04mm if there is no other specific requirements.
Seal ring and O ring
According to the customers’ requirements and working condition, eternal company would choose suitable
seal ring kit, seal ring brand include: Parker, Merkel, NOK, Guangzhou Rubber institute, Taiwan brand etc. Eternal company would supply suitable seal solution for their customer so that hydraulic cylinder has more lifetime, easy maintenance and simple repairing.
Tube and flange welding
The welding on cylinder tube and flange would be Ultrasonic tested every time, the welding seam would be
cleaned before machining. Eternal company ensure that every welding seam has no any leak during lifetime
1.Extensive production experience: more than 20 years manufacturing experience for honed tube and chrome plated rod, in Australia, Thailand, Brazil, India, Iran, Indonesia, South Africa and other countries have long-term buyers.
2.Advanced production equipment: cold drawing machine, honing machine, skiving & roller burnishing machine, straightening machine, polishing machine, heat treatment furnace, grinding machine, etc. We have professional technicians do regular scheduled maintenance on these machines to guarantee them work well.
3.High quality raw material: our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.
4.High precision: Honed Tube, inside surface roughness 02-0.4 um, straightness max 0.5/1000, strict tolerance DIN2391 H8. Skived & Roller Burnished Tube, inside surface roughness under 0.2 um, straightness max 0.2/1000, strict tolerance DIN2391 H8. Chrome Plated Rod, chrome layer 10 micron to 100 micron, strict tolerance ISO f7.
5.Strict quality control: we have professional in-house QC to inspect all products. We will do Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other tests in need before delivery.
6.Safe packing: an-rust oil on tubes and rods before delivery. Plastic caps on both ends to protect tube inside surface. Then be packed with seaworthy package or in wooden case.
