Features and Benefits

Easy to Install, Reducing Installation Costs
Easy installation is a significant benefit of electric linear actuators, especially compared to hydraulic or pneumatic systems. Electric linear actuators are generally self-contained units with a motor, gears, and a leadscrew.
Low Maintenance Design
Easy to maintain after installation
Long Product Life Expectancy
The use of high-quality materials and engineering practices build actuators that can withstand repeated cycles of operation and varying loads.
Ball Screw or Acme Screw
Ball screws, with their recirculating ball bearings, offer higher efficiency, precision, and speed capabilities, making them suitable for demanding applications. ACME screws, with their sliding friction design, are more robust and better suited for applications with high vibrations or vertical orientations where self-locking is desired.
Ductile Iron Housing
Ductile iron offers significantly higher tensile strength compared to traditional cast iron, making it well-suited for high-stress applications.
Chrome Plated Translating Tube
The chrome-plated translating tube is a key component of heavy-duty linear actuators, contributing to their reliability, durability, and ability to operate in challenging conditions.
Adjustable End of Stroke Limit Switches
Define the exact stroke length needed for their application, even if it's shorter than the actuator's maximum stroke.
Double Clevis Mounting
Provides the ability to pivot on both ends making this mounting method ideal for applications where the actuator needs to accommodate changes in angle or follow a fixed arc during operation.
