In recent years, advancements in automation technology have significantly impacted various industries, including healthcare. One notable innovation is the integration of electric actuator in OT (Operating Theatre) tables, revolutionizing surgical procedures and patient care. In this blog post, we will explore the importance of electric actuators in healthcare furniture, focusing on OT tables, and how they enhance the overall surgical experience. We’ll delve into their function, working principles, types, manufacturers in India, and the selection process to ensure optimal performance.

What is an Electric Actuator?

An electric actuator is a critical component of modern automation systems, responsible for converting electrical energy into precise linear motion. It acts as a driving force behind various applications, enabling smooth and accurate movements in different equipment and furniture, including massagers chairs, dental chairs, and, in our case, OT tables.

Function and Working Principle

The primary function of an electric actuator in an OT table is to control and adjust the table’s height, tilt, and other positions according to the surgeon’s requirements. It enables healthcare professionals to optimize patient positioning during surgical procedures, improving accessibility and reducing physical strain.

The working principle of electric actuators is based on linear motion, where an electric motor drives a lead screw or a ball screw mechanism to produce linear movement. As the motor rotates, the screw transforms the rotary motion into linear motion, pushing or pulling the actuator to achieve the desired position.

Types of Electric Actuator

Electric actuators come in various types, including push-pull linear actuators, telescopic electric actuators, compact linear actuators, and many more. Each type serves specific purposes, providing the flexibility and precision needed for different applications.

Electric Actuator Manufacturers in India

In India, the demand for electric actuators has grown significantly due to the expanding healthcare industry. Several reputable companies, such as Kathir Sudhir Automation Solutions, have emerged as leading manufacturers, providing high-quality electric actuators to meet the diverse needs of the healthcare sector.

Selecting the Right Actuator

Choosing the right electric actuator for an OT table is crucial for ensuring optimal performance and longevity. To make an informed decision, manufacturers often provide an actuator selection table, which outlines various specifications and features of each actuator model. Factors to consider during the selection process include load capacity, stroke length, speed, duty cycle, and IP rating for protection against dust and water.

Advantages of Electric Actuator in OT Tables

  1. Precision and Accuracy: Electric actuators offer precise control over table movements, ensuring surgeons can position patients accurately during surgery.
  2. Reduced Noise and Vibration: Compared to hydraulic or pneumatic systems, electric actuators operate quietly, providing a conducive environment in the operating theatre.
  3. Easy Integration: Electric actuators are compact and lightweight, making them easy to integrate into existing OT table designs.
  4. Energy Efficiency: Electric actuators consume less energy, reducing overall operational costs.
  5. Increased Patient Comfort: The smooth and gradual movements facilitated by electric actuators enhance patient comfort during surgery and recovery.


The integration of electric actuators in OT tables has revolutionized the healthcare industry, providing surgeons with precise control over patient positioning during surgical procedures. The selection of the right electric actuator is crucial for optimizing performance and ensuring a positive impact on patient care. With the continuous advancements in automation technology, we can expect even more innovative applications of electric actuators in the healthcare sector, further enhancing patient outcomes and overall surgical experience.
