If you are looking for high-quality precision tubes with smooth internal surfaces and excellent dimensional accuracy, our SRB Tubes (Skived and Rolled Burnished Tubes) are the perfect solution.
Manufactured using advanced cold drawing and skiving & roller burnishing technology, SRB tubes deliver exceptional surface finish, tight tolerance, and high strength — ideal for critical hydraulic and pneumatic applications.
What Is SRB Tube?
SRB Tube stands for Skiving & Roller Burnishing Tube (also known as Seamless Rolled Bright Tube).
It is a cold-finished seamless tube with an excellent internal surface finish (Ra ≤ 0.2–0.4 μm) and accurate ID tolerance.
👉 Compared to conventional honed tubes, SRB tubes offer superior roundness, better surface hardness, and longer service life.

✅ High surface finish — Ra ≤ 0.4 μm
✅ Tight dimensional tolerance (H8 / H9)
✅ High strength and durability
✅ Superior straightness
✅ Better sealing performance in hydraulic systems
✅ Longer service life compared to honed tubes
✅ Easy installation and maintenance
Our SRB tubes are widely used in hydraulic and pneumatic systems where smooth inner surfaces are essential for performance and efficiency:
Hydraulic cylinders
Pneumatic actuators
Heavy machinery
Construction equipment
Industrial presses
Material handling systems
Agricultural equipment
🏭 Advanced manufacturing technology — high precision machining and quality inspection.
🌍 Global standard compliance — DIN, ASTM, EN.
📏 Custom sizes & lengths available.
