A skived and rolled tube, also known as a skived and roller burnished tube, is a precision steel tube manufactured through skiving and roller burnishing processes.
The skiving process removes a thin layer of material from the inner surface, while roller burnishing compresses the surface to achieve a smooth and hard finish.
This type of precision tube is widely used in hydraulic cylinder barrels, pneumatic cylinders, and high-performance machinery.
It is also referred to as SRB tube, hydraulic cylinder tubing, or precision finished tube in industrial applications.
Skived and rolled tubes provide superior surface finish with roughness typically Ra ≤ 0.2μm.
The roller burnishing process improves surface hardness, reducing wear and extending the service life of hydraulic cylinders.
These tubes maintain excellent dimensional tolerance, ensuring accurate piston movement and improved sealing performance.
Compared with honed tubes, SRB tubes often deliver higher production efficiency and lower cost while maintaining comparable precision quality.
Most skived and rolled tubes are manufactured from seamless steel pipes such as ST52, CK45, SAE 1020, and 42CrMo4.
These materials provide high strength, good machinability, and reliable fatigue resistance under pressure.
For corrosion-resistant applications, stainless steel skived and roller burnished tubes are also available, especially in marine and chemical industries.
Skived and rolled tubes are primarily used in hydraulic cylinder barrels for construction machinery, agricultural equipment, and mining machines.
They are also widely applied in pneumatic cylinders, material handling systems, and industrial presses.
Due to their precise dimensional tolerance and smooth bore surface, SRB tubes are ideal for high-pressure hydraulic systems and heavy-duty equipment.
Other applications include injection molding machines, offshore platforms, and lifting equipment.
Available inner diameters range from 30mm to over 500mm, depending on hydraulic cylinder design.
Custom sizes are available upon request.
Standard tube lengths can reach up to 12 meters, with options for cutting and machining to specific requirements.
This flexibility ensures compatibility with different types of machinery.
The skiving and roller burnishing process achieves a surface finish of Ra ≤ 0.2μm.
This ensures smooth piston movement and reduces energy loss due to friction.
Straightness tolerance is typically ≤ 0.2/1000mm.
This accuracy guarantees stable operation of hydraulic cylinders under high load.
A honed tube is produced by abrasive honing, which removes material to achieve the desired surface finish and tolerance.
A skived and rolled tube, however, uses a skiving tool followed by roller burnishing, which not only improves finish but also compresses the surface for added hardness.
While both types of precision tubes are suitable for hydraulic cylinders, SRB tubes often provide better efficiency in production and improved wear resistance.
The choice depends on cost, performance needs, and specific application conditions.
Proper maintenance ensures long-lasting performance of SRB tubes in hydraulic systems.
Regular inspections should be carried out to detect corrosion, pitting, or scratches on the inner bore.
Using clean hydraulic oil and replacing worn seals prevents contamination and extends service life.
Storing skived and rolled tubes with protective coatings prevents rust before assembly in hydraulic cylinders.
Yes, skived and rolled tubes can be manufactured according to customer-specific requirements.
Customization options include inner diameter, length, wall thickness, and tolerance levels.
Special steel grades and surface treatments are available for high-pressure, marine, or corrosive environments.
Tailor-made SRB tubes provide optimal performance for OEM hydraulic cylinder manufacturers and industrial machinery builders.
