Description
Product Description
The ASHUN SO Series Low-Pressure Hydraulic Cylinders are developed for light industrial applications and precision automated production lines. Their smooth cylindrical exterior effectively minimizes installation blind spots within machinery; unlike heavy-duty welded designs, the SO series' exclusive threaded rear cap craftsmanship ensures high system sealing integrity while allowing facility personnel to perform routine inspections and internal part replacements much more rapidly.
Paired with versatile mounting styles such as flat tail, foot, and clevis, this series integrates smoothly into various micro or compact equipment mechanisms, demonstrating exceptional operational smoothness in space-constrained environments.
Product Features
- Compact Specifications: Available in three compact bore sizes—Ø20, Ø30, and Ø40mm—tailored specifically for miniaturized installation spaces.
- Quick-Release Threaded Barrel: The rear cap utilizes high-precision threaded locking for non-destructive disassembly, significantly reducing maintenance time and costs.
- Lightweight Material Options: Cylinder tubes can be flexibly configured in carbon steel, stainless steel, or aluminum alloy based on the operating environment to effectively reduce overall equipment load.
- High-Temperature Adaptability: The entire series can be upgraded with high-temperature VITON seals, ensuring long-lasting operation in environments up to 150°C.
Solutions
Construction Machinery
Construction equipment operates in punishing environments characterized by extreme climates, heavy dust, and intense vibration. Equipment stability is the ultimate key to maintaining project schedules. ASHUN provides highly durable custom hydraulic cylinders and high-torque rotary actuators specifically engineered for excavators, loaders, and heavy-duty construction vehicles. Our solutions feature superior anti-side-load capabilities and extreme precision, ensuring flawless performance under heavy loads, high pressure, and continuous operation—conquering the toughest job site challenges.
Lifting Equipment
Material handling equipment carries extreme risks to human safety and valuable assets; every lift and rotation must be flawless. For aerial work platforms (AWPs), cranes, tail lifts, and jacking systems, ASHUN delivers custom hydraulic cylinders integrated with fail-safe mechanisms and rotary actuators for high-precision positioning. We guarantee smooth, zero-leakage performance under heavy aerial loads and high-frequency lifting conditions.
Military and Aerospace
In defense and aerospace applications, mission success is paramount, and hydraulic system failures are strictly zero-tolerance. Certified by the AS9100 Aerospace Quality Management System, ASHUN provides custom hydraulic cylinders and high-torque rotary actuators engineered with exceptional safety factors for armored vehicles, radar antennas, and ground support equipment (GSE).
Agricultural Machinery
From soil preparation to harvesting, agricultural machinery is constantly exposed to mud, dust, and erratic weather. ASHUN provides weather-resistant, leak-proof custom cylinders and precision rotary actuators for tractors, combine harvesters, and diverse attachments. Our high-load capacity ensures uninterrupted, high-efficiency operation during critical farming seasons.
Medical
Patient safety hinges on the smooth, silent, and hygienic operation of medical actuation systems. ASHUN designs custom precision hydraulic cylinders for surgical tables, high-end hospital beds, and patient lifts. Featuring medical-grade cleanroom standards, ultra-quiet operation, and integrated fail-safe valves, we deliver the highest level of stability and protection.
Smart Automation/Industry 4.0 or Robotics Industry
In the era of smart manufacturing, heavy robotics and automated equipment require actuation that combines high power density with precise data feedback. ASHUN empowers heavy-duty robotic arms, AGVs, and automated production lines with smart-sensor-integrated cylinders and high-precision rotary actuators, seamlessly bridging the gap between traditional hydraulics and Industry 4.0 servo-hydraulics.
