Q1: What is a honed tube used for?
A: Honed tubes are mainly used for manufacturing hydraulic and pneumatic cylinders. They provide a smooth inner surface and high precision, ensuring proper sealing and long service life.
Q2: What tolerance can you achieve for the inner diameter?
A: We can achieve H8 / H9 tolerance, and tighter tolerance can be customized according to your requirements.
Q3: Do you support custom sizes or special requirements?
A: Yes, we support full customization including ID, OD, length, tolerance, and surface roughness.
Q4:What is the surface roughness of the inner wall?
A: The standard roughness is Ra ≤ 0.8 μm, and we can also offer Ra ≤ 0.4 μm for high-precision applications.
ASTM B49,IEC 60228,GB/T 3953,Other standards can be produced according to project specifications.
Q5:What materials are available?
A: We commonly supply:ST52 / E470,SAE 1026 / 1045,20MnV6,Alloy steel (4140 / 4130),Stainless steel (304 / 316 optional)
Q6:What is the difference between honed tube and skived & roller burnished tube?
A: Honed tubes are processed by honing for higher precision, while skived & roller burnished tubes are more cost-effective for large sizes and mass production.
Q7:How do you ensure quality?
A: Each tube is inspected through:Dimension measurement,Roughness testing,Mechanical property testing,Ultrasonic testing (UT)
