With over 70 years of expertise, we have established ourselves as one of the most reliable spring manufacturers in the UK. We have a wealth of experience in providing ISO 9001-certified solutions for a range of different industries, from specialised bespoke products to higher volume stock orders.
We supply both custom springs and an extensive range of stock solutions, catering to various industrial needs. We manufacture and supply both single coil torsion springs and double coil torsion springs, which are two single torsion springs connected. Whether you require a unique component tailored to demanding conditions or a ready-to-ship option, our team is ready to assist.
There are certain applications that may require the design and manufacture of a bespoke component, especially for those with unique demands or environmental considerations. We offer comprehensive design and engineering support, from initial concept to end product.
Our engineering team use advanced CAD CAM software to create custom torsion springs in a range of shapes and sizes, including small, large, extended length and double torsion springs. Our torsion springs are made in dimensions of 0.15mm to 8mm with wire, and the body diameter, length, pitch and choice of material are all down to customer specifications. We take into account the environmental conditions, stresses, life-cycle requirements and any other relevant factors to create springs that are adapted to their application.
As part of the internationally respected Lesjöfors Group, we supply both standard torsion springs in the fine to medium weight category and custom torsion spring solutions. Browse our full selection of wire springs in our spring catalogue, where you can find:
Stainless Steel Torsion Springs (EN 10270-3-1.4310)
When using torsion springs, performance and longevity are influenced by the applied torque angle. Refer to the following guidelines for lifespan expectations:
The maximum permitted torque is denoted Mn, and the torque angle at Mn is shown as w in technical tables. Use of the spring within 70-80% of its maximum torque range significantly improves its durability.
With over 70 years of experience in creating torsion springs, we are experts in producing components for demanding applications across the most high-pressure environments. Our modern CNC equipment allows us to quickly produce torsion springs with excellent precision and minimal finishing.
Torsion springs have a linear spring characteristic, meaning the torque output increases proportionally with the degree of rotation. This makes them ideal for consistent, reliable mechanical energy storage and release in rotational systems.
From concept through to final product, our team ensures your springs are durable, reliable, and able to withstand their intended working conditions.
In addition to our manufacturing capabilities, we provide a full suite of services designed to streamline the production cycle. This includes surface treatments, sub-assembly services, and prototyping for development and testing.
We manufacture a broad range of different springs, including compression springs and tension springs, allowing you to source all your spring components from a single trusted supplier. Whatever your spring requirements, European Springs & Pressings ensure precision, reliability, and expert support from start to finish.
Torsion springs are a type of coiled spring that work via a rotational motion known as torsion. They are used when there is a need for rotational movements of components.
The most common design for a torsion spring is the cylindrical wound design, which consists of a coiled metal wire, in a left- or right-hand, clockwise or anti-clockwise direction and usually has legs, to which a force can be applied.
Torsion springs are usually mounted upon a Mandrel and the force is applied to the spring axially. The rotational motion allows a flexible object to store mechanical energy. This exerts a force, known as torque, in the opposite direction, proportional to the amount it is rotated. As components rotate around the centre of the spring, it will attempt to push them back to their original position.
Torsion springs can be made single torsion or double torsion, which doubles the output force.
Torsion springs have a linear spring characteristic, i.e. if a spring is turned 10˚ to provide torque of 1 Nmm, the same spring will provide a torque of 2 Nmm at 20˚ rotation.
Torque is equal to force x leg length: M = F x A. The closer to the end of the leg the load is applied, the less counterforce is created.
Single torsion springs consist of one coil and are suitable for applications with moderate torque needs. Double torsion springs combine two coils, which increases torque output and improves balance.
Lifespans of torsion springs can vary depending on the application, material, and operating conditions. We recommend regular inspection and replacement after extensive use or visible wear. High-stress environments have the potential to shorten the spring’s longevity, so preventative maintenance is essential.
Here is an inclusive list of the main sectors and applications where Torsion Springs improve designs and make a positive difference.
And even if we don’t have exactly the tool we need, European Springs’ in house technology enables us rapidly to design and make complex tools, allowing us to offer more competitive prices.
