If your equipment relies on controlled rotational force—whether in automated gates, conveyor systems, or industrial braking mechanisms—torsion springs are likely doing the heavy lifting behind the scenes.
These compact powerhouses are built to handle repeated torque, cycle after cycle. But not all torsion springs are created equal. The materials, winding direction, leg configuration, and number of coils all affect how your spring performs in real-world conditions.
This guide breaks down the practical applications of torsion springs across industrial settings and outlines what you need to know when specifying a custom-built spring for your machinery. Whether you’re replacing a worn-out part or sourcing components for new builds, accuracy in design and manufacturing is critical. Here’s how to get it right.
Why Torsion Springs Are Used in Industrial Equipment
Torsion springs play a key role in a wide range of industrial systems due to their ability to:
- Control motion with precision
- Store rotational energy efficiently
- Operate under high stress and repeat cycles
- Handle both clockwise and counterclockwise torque
Industries that rely on automation, heavy-duty machinery, and repetitive motion systems depend on torsion springs for consistent performance and safety.
Common Industrial Applications of Torsion Springs
1. Automated Assembly Equipment
Torsion springs help regulate motion and positioning in automated machinery, ensuring parts rotate at the correct speed and angle.
- Arm and lever return mechanisms
- Motor-driven part feeders
- Hinged assembly platforms
2. Conveyor Systems
In conveyor systems, torsion springs stabilise rotating components and allow flexible movement in tensioned rollers or gates.
- Roller tensioners
- Adjustable spring-loaded guides
- Trap doors and diverters
3. Clutches and Brakes
Torsion springs help engage and disengage clutches or braking systems, particularly in vehicles or industrial presses.
- Drum brakes
- Clutch return mechanisms
- Torsion-based dampening systems
4. Industrial Valves and Dampers
For systems controlling air, gas, or liquids, torsion springs provide the force needed to return valves to a closed or default position.
- Butterfly valves
- Pressure-release dampers
- Emergency shut-off valves
5. Robotics and Precision Tools
In robotic arms and precision machinery, torsion springs control rotation angles and apply torque consistently.
- Jointed robotic arms
- CNC tool changers
- Motorised hinges
Types of Torsion Springs for Industrial Use
Depending on the application, torsion springs are available in various shapes and configurations:
- Single Torsion Springs – Basic coil with arms extending in the same or opposite directions.
- Double Torsion Springs – Two coils wound in opposite directions, joined at the centre for balanced torque.
- Spiral Torsion Springs – Flat spring material wound into a spiral, used in compact torque applications.
Choosing the Right Material
Industrial torsion springs must withstand pressure, heat, and corrosion. Boynes Springs offers custom torsion springs in high-performance materials like:
- Stainless Steel (302, 304, 316) – Corrosion-resistant, ideal for harsh environments
- Spring Steel – Durable and cost-effective for high-stress settings
- Inconel or Alloy Steels – For extreme heat or chemical exposure
Design Considerations
When specifying an industrial torsion spring, you’ll need to consider providing your torsion spring manufacturer with the following details:
- Wire diameter – Affects torque capacity and stress tolerance
- Inner and outer coil diameters – Determine how much space is needed for mounting
- Leg length and shape – Customised to suit application requirements
- Direction of wind (left-hand or right-hand) – Matches the rotational force direction
- Number of coils (active and total) – Impacts spring strength and flexibility
Key Benefits of Torsion Springs in Industrial Applications
- Durability – Designed to withstand repeated cycles under heavy load
- Compact Design – Stores torque efficiently in a small footprint
- Customisability – Can be made to exact specs for machinery and components
- Energy Efficiency – Stores and releases energy without external power
- Reduced Downtime – Reliable performance in critical operations
Work with a Trusted Torsion Spring Manufacturer
For industrial torsion spring applications, precision is everything. At Boynes Springs, we manufacture high-performance custom torsion springs for a wide range of industries—from mining to manufacturing.
We do not design springs for your application, but we manufacture exactly to your specifications. To order a torsion spring, you’ll need to supply:
- A detailed drawing or sketch
