Description
Product Description
The ASHUN RA30 Series Hydraulic Rotary Actuators are robust power components crafted for heavy engineering and demanding industrial conditions. To meet the installation demands of large machinery, these actuators provide both FA front flange and LA foot mount standard configurations. They also support custom clevis mount development for specialized attachments like heavy-duty tilting mechanisms and large manipulator joints. This grants engineers significant structural layout flexibility and bending support when designing mining equipment or large excavators.
Inheriting precision double-helix meshing technology and a zero-leakage internal design, the RA30 series actuators feature a highly rigid load-bearing structure, ensuring the positioning accuracy and actuation stability of large cantilevers and heavy-duty attachments in harsh engineering environments.
Product Features
- Heavy-Duty High-Pressure Actuation: Engineered for large machinery, demonstrating stable driving capability and durability under 210 bar (3000 psi) operating pressure.
- Dual Standard Mounting Bases: Offers FA front flange and LA foot mount options to reliably fit the chassis or joints of various large equipment.
- High-Rigidity Load-Bearing Structure: Combined with a zero-leakage internal design, it ensures the equipment possesses high bending resistance and stable locking under heavy loads.
- Custom Project Support: Capable of developing exclusive clevis mounts for heavy-duty tilting mechanisms and large material handling manipulators, fulfilling the integration needs of front-end attachments.
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.
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.
