What Are Torsion Springs?
Torsion springs are a type of industrial spring that stores and releases energy by twisting or rotating around a central axis. They are chosen for their ability to provide precise torque, maintain tension, and control rotational motion, making them essential in many mechanical systems.
Apex’s torsion springs are made from a variety of materials, including chrome silicon, music wire, pre-coated material, and stainless steel. They are offered in wire sizes ranging from .018” to .156” in diameter.
Torsion springs are a subset of wire-formed components, and their popularity can vary depending on the needs of specific industries.
Here are some popular types of torsion springs and the various industries where they are commonly used:
Single torsion springs are the most basic type of torsion spring, consisting of a helical coil of wire wound in a single direction. When you twist the ends of the spring, it stores energy, and when released, it exerts a torque or rotational force.
Used in various vehicle components like door handles, trunk lids, and seat recliners.
Aero Space Industry
Used in control surfaces, landing gear, and flight control systems.
Used in various types of machinery for controlling and positioning components.
Double torsion springs consist of two helical coils connected by a central element. When you twist the ends of the spring, both coils wind or unwind simultaneously, producing a torque in opposite directions. Double torsion springs are often used when a counterbalancing effect is required.
Often used in medical instruments, surgical tools, and devices requiring precise torque control.
Used in various components like switches and connectors.
When a counterforce or torque is needed in both directions.
Close-wound torsion springs are wound tightly with minimal space between the coils. These springs are ideal when space is limited and high torque is needed. They offer more resistance to bending and can provide a strong return force.
These springs are commonly used to counterbalance the weight of garage doors. (NOTE: Apex does not manufacture garage door springs)
Used in machinery such as plows, cultivators, and more to provide torsion and resistance.
Various machines and equipment use close-wound torsion springs to torque and rotation control.
Automotive and Transportation
Used in vehicle suspensions and seating systems.
Found in recliners, chairs, and other furniture pieces.
Used in machinery like hay balers and seeders.
Torsion springs can have various leg configurations, such as straight legs, hinged legs, or other custom shapes. The leg design can impact the spring’s behavior and how it fits into the overall system.
These are employed in conveyor systems, assembly line equipment, and other automation uses.
Oil and Gas Industry
Used in valves, wellhead equipment, and drilling tools.
Found in various sports equipment like golf clubs, fishing rods, and exercise machines.

Advantages of Using Torsion Springs
Torsion springs offer several advantages due to their unique design and characteristics. Here are some of the advantages of using torsion springs
Torsion springs are typically more compact and space-efficient than other types of springs, such as compression or extension springs, making them suitable when limited space is available.
Smooth and Controlled Motion
Torsion springs provide smooth and controlled rotational motion, which is crucial when jerky or sudden movements are undesirable.
Torsion springs can provide a consistent and reliable force throughout their operating range, making them suitable when constant torque or tension is required.
The torque output of torsion springs can often be adjusted by changing parameters like the wire diameter, coil diameter, or the number of coils, allowing for customization to meet specific requirements.
Reliable for Repetitive Cycles
Torsion springs are well-suited for many repetitive cycles, as they can maintain their performance characteristics over many cycles without significant degradation or failure.
