Custom Torsion Springs
Stanley Spring & Stamping is the top choice for all of your torsion spring design, production, and manufacturing needs. We opened our doors to the public in 1944 and are proud of our experience providing the highest quality products in the industry. We work with every client to ensure the right spring is designed for their specific application. With a wide variety of sizes, materials, and thicknesses, we’ve successfully designed torsion springs for many different uses.
Our team is committed to providing clients with superior customer service, reliability, precision, and trustworthiness. Our team of skilled experts will design and manufacture custom torsion springs to fit any project requirements including, home appliances, and outdoor power equipment, among many other applications. If a customer isn’t sure what torsion spring design they need, we’ll work with them to review their specific requirements and produce a custom torsion spring that meets those requirements.

Torsion Spring Design
There are some important design elements that need to considered to ensure the proper functioning of either a single or double torsion spring, including:
- Spring Rate – This is the angular return torque produced per angular displacement unit.
- Wind - Torsion spring wind orientations can be left handed, right handed or double torsion.
- Maximum Level of Deflection – This is the maximum angular deflection a torsion spring can withstand before failing or being damaged.
Stanley Spring and Stamping can produce steel torsion springs in either English (Imperial) or metric units. Contact us to specify what unit of measurement you need for your application, along with other design details for your custom torsion springs. Our goal is to meet your exact needs and specifications.

Torsion Spring Sizes
When designing and producing torsion springs, the dimensions heavily influence the final design. The following measurements need to be taken into consideration:
- Inner Diameter must be precise in order to allow a spring to go over a mandrel with the proper amount of operational clearance.
- Outer Diameter must allow a spring to fit into a design cavity while still giving it proper clearance to freely function and clear outer housings.
- Spring Length must be exact to allow the spring coil and legs to fit in its designated spot in the device.
- Wire Diameter is the diameter of the coil wire itself and must be correct for the specific application.
- Length of Spring Legs is important to consider, as the legs must fit correctly into their supporting structures in order for the spring to operate as designed.
Torsion spring sizes are a critical design element and our experienced team works with each customer to ensure the correct dimensions are utilized for their specific application.
Torsion Spring Configurations
Torsion Springs are engineered to have a rotational actuation and will provide an angular return- pressure force. As it relates to the design and characteristics of a spring’s legs, there are a variety of options available, since not all springs will attach the same way in every device. The attachment of the spring to the supporting structure can be accomplished in many ways. Here is what to consider when evaluating the specifications of torsion spring legs:
- Style of Leg Ends
- Length
- Degree of Angle
Torsion springs that have a straight or parallel on the same side design characteristics will have a zero-degree leg angle. Common leg end designs include:
- Short Hook End Design
- Straight Offset
- Longer Hood End Designs
- Hinged
- Straight Torsion
Double Torsion Springs
Double torsion springs have many common characteristics with single torsion springs; however, they are unique in some ways. Double torsion springs involve the use of two sets of coils, one being coiled with a right-hand orientation and the other being coiled in a left-handed direction. The two sets of coils are normally connected by an unwound piece in between the coils and work in parallel. The total torque output of a double torsion spring is made up of the sum of the torque exerted by each individual coil wind. These springs are commonly used to lift, rotate, offset, and center rotating loads. Please contact us for more information on our double torsion spring manufacturing capabilities
