Why Choose SRB Honed Tubes?
Skiving and roller burnishing combine fast material removal with controlled bore finishing and surface strengthening.
Controlled Bore Dimensions
Precision skiving establishes the required inner diameter, while roller burnishing helps maintain a consistent finished bore.
Smooth Inner Surface
Roller-burnished surfaces can achieve very low roughness, supporting smooth piston movement and reliable seal contact.
Work-Hardened Bore
Roller burnishing cold-works the inner surface, improving surface hardness and resistance to wear in repeated cylinder movement.
Controlled SRB Processing from Tube to Finished Bore
Every SRB tube passes through controlled sizing, skiving and roller burnishing before final inspection, with bore dimensions and surface quality checked before shipment.
WHY EAST AI
SRB performance depends on more than surface finish. Tube material, bore dimensions, straightness and inspection all affect the finished cylinder.
What Buyers Value in SRB Tubes
For hydraulic cylinder buyers, consistent bore quality matters as much as the tube itself.
Controlled inner diameter and surface finish help reduce fitting problems during cylinder assembly and support repeatable production.
A smooth, controlled bore helps support piston and seal performance throughout repeated cylinder movement.
Consistent specifications across recurring orders help manufacturers maintain the same cylinder performance from batch to batch.

Frequently asked questions
SRB stands for Skived & Roller Burnished. The process uses precision skiving to size the bore, followed by roller burnishing to smooth and strengthen the inner surface.
Both are precision-finished hydraulic cylinder tubes. SRB uses skiving followed by roller burnishing, while conventional honing uses abrasive stones. SRB is widely used where repeatable bore quality and efficient production are required.
SRB tubes can achieve a very smooth inner surface, with commonly specified values around Ra 0.2–0.4 μm depending on material, diameter and production requirements. Final values should be confirmed against the required specification.
Common requirements include ISO H7, H8 and H9, depending on tube size, material and application. The required tolerance can be confirmed before production.
Yes. SRB tubes are widely used as hydraulic cylinder barrels where controlled bore dimensions, smooth inner surfaces and repeatable production quality are required.
Yes. Requirements such as inner diameter, wall thickness, length, material, tolerance and surface finish can be reviewed according to the cylinder design and production requirements.
