Rotary Actuators

Hydraulic rotary actuators are compact, high-torque actuators that convert hydraulic pressure into precise rotary motion using a helical gear mechanism. These actuators are widely used in industries such as aerospace, defense, construction, marine, and material handling due to their ability to provide high torque output in a small footprint.

How They Work

Helical hydraulic rotary actuators operate based on the principle of helical gearing. Inside the actuator, a combination of a helical spline, a piston, and a ring gear work together to convert linear hydraulic pressure into rotational motion. When pressurized hydraulic fluid is introduced into the actuator, it moves the piston, which engages with the helical gear teeth to produce smooth rotary movement.

Key Features & Advantages

• High Torque Output: Capable of delivering high torque in a compact design.

• Precise Positioning: Provides smooth and controlled motion.
• Compact & Lightweight: Suitable for applications where space and weight constraints are critical.
• Durable & Reliable: Designed to withstand harsh environments and heavy-duty operations.
• Bidirectional Operation: Can rotate in both directions based on hydraulic input.

Applications

• Aerospace & Defense: Used in missile launchers, weapon systems, and aircraft control surfaces.

• Construction Equipment: Found in excavators, backhoes, and heavy lifting mechanisms.

• Marine & Offshore: Used in ship steering systems, subsea equipment, and offshore drilling rigs.

• Material Handling: Applied in robotic arms, conveyor systems, and automated machinery.

• Industrial Automation: Helps in precise rotation of workpieces in manufacturing processes.

The Rotational Angle is : 0° to 360°
