Here is a comprehensive list of companies in India that manufacture actuators, followed by a specific list of those that are publicly traded on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE).
Understanding Actuators
Actuators are essential components in industrial automation and machinery. They are devices that convert a source of energy (typically electric, pneumatic, or hydraulic) into physical motion. This motion can be linear (in a straight line) or rotary (circular). They are critical in a vast range of applications, from opening and closing valves in a factory to controlling flight surfaces on an aircraft.
Comprehensive List of Actuator Manufacturers in India
This list includes a mix of publicly listed, private, and multinational companies with manufacturing operations in India.
Electric Actuators
These actuators use electrical energy to produce mechanical motion. They are known for their precision, control, and ease of integration with modern control systems.

Actuator Manufacturers Listed on NSE & BSE
For investors looking to participate in this sector, here are the companies from the list above that are publicly traded on Indian stock exchanges.
| Company Name | Stock Ticker (NSE / BSE) | Type of Actuators Manufactured |
| Honeywell Automation India Ltd. | NSE: HONAUT BSE: 517174 | Electric actuators for building and process automation. |
| Siemens Ltd. | NSE: SIEMENS BSE: 500550 | Electric actuators for industrial process control. |
| Wipro Ltd. (Wipro Enterprises is an unlisted arm) | NSE: WIPRO BSE: 507685 | While Wipro Ltd. is listed, its hydraulic actuator business is part of Wipro Enterprises (P) Ltd., which is an unlisted entity. However, the performance of this business contributes to the overall Wipro ecosystem. |
| Veljan Denison Ltd. | BSE: 505232 (Listed only on BSE) | Hydraulic cylinders and actuators. |
Important Note for Investors:
- Diversified Businesses: Companies like Siemens and Honeywell are large conglomerates. While they manufacture actuators, this forms only one part of their overall business. Their stock performance will be influenced by all their business segments, not just actuators.
- Pure-Play vs. Conglomerate: There are very few “pure-play” actuator manufacturers listed on the Indian stock market. Most are either part of larger engineering conglomerates or are unlisted private limited companies or Indian subsidiaries of foreign MNCs (like Rotork, AUMA, and Emerson).
- Rotex Automation is a significant Indian player but remains a privately held (unlisted) company as of now.
When considering an investment, it’s crucial to analyze the company’s entire product portfolio and market position, not just its presence in the actuator segment.
