SRB Tubes(Skived and Roller Burnished Tubes)
SRB Honed Tubes(Skived and Roller Burnished Tubes) Manufacturer
- Superior Surface Finish
- The SRB process ensures an excellent inner surface finish (Ra ≤ 0.2~0.4 μm), reducing friction, improving sealing performance, and extending equipment life.
- High Dimensional Accuracy
- SRB Honed Tubes achieve tight dimensional tolerances (H7-H9), ensuring precision and consistency for high-performance applications.
- Increased Surface Hardness
- The roller burnishing process forms a hardened surface layer, improving wear resistance and fatigue strength for enhanced durability.
- Reduced Processing Defects
- The combination of skiving and burnishing eliminates machining defects such as cracks and pores, ensuring higher quality tubes.
- Improved Production Efficiency
- The SRB process integrates skiving and burnishing in one step, reducing manufacturing time and cost.
- Extended Seal Life
- The smooth, burr-free inner wall reduces wear on seals, minimizing maintenance and replacement frequency.
- Lower Energy Consumption in Hydraulic Systems
- The smooth inner surface reduces fluid flow resistance, improving hydraulic system efficiency and saving energy.
- Versatile Applications
- SRB Honed Tubes perform well under high pressure, high temperature, and demanding conditions, making them suitable for hydraulic cylinders, pneumatic systems, and heavy machinery.
