Description
Powerful and Reliable THM SAM Series Rotary Actuator
The THM SAM Series Rotary Actuator is designed to produce high-performance, accurate rotary motion in a compact footprint from THM Hydraulics. Recognized by engineers and equipment manufacturers worldwide for its reliability, this hydraulic rotary actuator offers consistent torque and positioning control in a variety of demanding industrial applications.
The SAM Series provides durability, accuracy, and versatility for applications requiring high load capacity, speed, and excellent performance at full and low speeds. It is an excellent motion solution for upgrading existing systems or applications requiring new designs.
What is a Rotary Actuator?
A rotary actuator is a mechanism that translates hydraulic or electronic energy into rotary motion. In contrast to linear actuators, which deliver a straight line movement, they deliver turning motion with high torque, which is used in machinery, automation, mobile equipment, and heavy-duty applications. What THM’s SAM Series brings, however, is that it generates torque more efficiently and comes in a sealed box design that is suitable for confined spaces and harsh environments.
THM SAM Series Rotary Actuator Important Features
Space Saving: The SAM Series provides high torque output in a small size for projects with limited space.
Robust Torque of Operation: This rotary cylinder actuator is built to be rugged enough to bear heavy loads and run constant torque under tough conditions.
Smooth and precise: Its low or no backlash rotation enables smooth and precise movement along the axis, which is suitable for precision positioning.
Long-Lasting Design: Engineered from tough materials and hard seals to withstand high pressure and hostile environments.
Flexible mounting options: Multiple mounting configurations for easy integration of electric rotary actuators into multiple industrial setups.
What Makes a Hydraulic Rotary Actuator Stand Out
For industrial applications, hydraulic rotary actuators, such as the THM SAM Series, provide many advantages over their electric counterparts:
Higher Power Density: Delivers more torque from a smaller volume
Shock Load Resistance: Preferred for applications with abrupt load variations.
Robustness: Functionally built for dusty, humid, or high-temperature operating environments.
Nonetheless, if your application needs a quicker response or is integrated with electronic systems, electric rotary actuators and rotary servo actuators are usually the better choice for their digital control features. Depending on your specifications, THM has solutions for hydraulic and electric actuation needs.
Typical Applications
The THM SAM Series is a rotative actuator that is perfect for the following:
- Construction and earth-moving equipment
- Equipment for Marine and Offshore Applications
- Farm automation solutions
- Industrial Robotics & Material Handling
- Mining and drilling rigs
This versatility makes it a leading option in fields where space economy and efficiency of rotation are essential.
