Build-to-Order Cylinders for Harsh Environments #
ASHUN’s customized hydraulic cylinders are engineered to order rather than held as predictive inventory. The company combines barrel structures and valve block integration developed through decades of OEM production for Japanese Tier-1 hydraulic component manufacturers, providing reliable fluid power solutions for global markets.

Design Features #
- Precision custom engineering (build-to-order) — End-to-end cylinder engineering tailored to the installation environment and stroke, without reliance on stock sizes.
- World-class OEM capacity and quality — Scalable production capacity of 20,000 units per month. ASHUN has been KYB Corporation’s exclusive overseas OEM partner since 2002.
- Versatile configurations and valve block integration — Telescopic, piggy-back and re-phasing cylinders, with cartridge valves integrated into the cylinder to maximize space utilization.
- Extreme precision machining and contamination protection — Bore sizes up to 500 mm, with assembly cleaning protocols and strict foreign object debris (FOD) control.
- Advanced automated manufacturing — Automated machining and welding reduce human error and maintain consistent precision from one-off custom builds to volume production.
Product Series #
- Custom Solutions — Tailored for special operating conditions and extreme environments that standard products cannot accommodate, covering collaborative design, sample verification and mass production.
- MO Series — Cast iron tie-rod cylinders for factory automation and general machinery, with flexible mounting configurations for medium-pressure applications.
- HO Series — Medium-duty tie-rod cylinders with a highly rigid structure for medium-pressure industrial environments and medium-sized machinery.
- FO Series — Medium-duty tie-rod cylinders for space-constrained equipment requiring stable thrust in a compact footprint.
- SO Series — Low-pressure cylinders for space-constrained equipment, with a threaded rear cap that simplifies routine maintenance.
- RO Series — Welded cylinders for medium-duty industrial environments, with high-strength welded construction for pressure resistance and leak prevention.
- CRO Series — Welded cylinders with a dedicated front oil port configuration that optimizes internal piping layouts while maintaining leak prevention.
Typical Applications #
- Excavators, loaders and heavy construction vehicles
- Aerial work platforms, cranes, tail lifts and jacking systems
- Tractors, combine harvesters and agricultural attachments
- Surgical tables, hospital beds and patient lifts
- Factory automation, machine tools and general industrial machinery
