Precision-honed inner surfaces and stable tolerances support smooth piston movement, reliable sealing performance, and long service life across different hydraulic cylinder applications.
Accurate honing and controlled surface roughness ensure smooth piston movement and reliable sealing, reducing friction, minimizing leakage risks, and significantly extending the service life of hydraulic cylinders.
Strict straightness and roundness control minimizes assembly difficulty, prevents uneven wear, and allows hydraulic cylinder components to align correctly during installation and long-term operation.
In-house production and full inspection before shipment ensure stable tolerances and repeatability, helping you maintain consistent cylinder quality across batches and reduce after-sales issues.
“Since switching to EAST AI honed tubes, our cylinder assembly process has become smoother, and sealing performance is much more consistent.”
“The inner surface quality is very stable, which helps us reduce after-sales issues.”
“Reliable delivery and consistent tolerances make EAST AI easy to work with for repeat orders.”
We understand that honed tubes are not just raw materials—they directly affect the performance and reputation of your hydraulic cylinders.
With in-house honing, skiving & roller burnishing, straightening, and inspection, EAST AI maintains full control over quality and delivery, giving you confidence in every batch, whether for standard models or customized cylinder designs.
Our honed tubes are widely used in industrial, mobile, agricultural, and construction hydraulic cylinders.
We supply honed tubes with smooth inner surfaces designed to support reliable sealing and long service life.
