Wire forms can have a shape that is limited almost only by fantasy. Many of them have some kind of spring functionality, for example some quick fastening applications. In most products, the material is stressed in bending and they can be looked upon as leaf springs made from wire. Wire forms are manufactur

Multi-coil wave springs are made from flat-rolled spring wire that is coiled to a helical shape and the coils are at the same time given a sinus shaped wave form. The force-deflection relation is created by flattening out the wave form when the spring is compressed. The function is hence like a helically shaped leaf spring.

Volute Springs are used as compression springs and made from flat material coiled to a volute. The coils of the material overlap each other and are guided radially by each other during compression, thus giving the spring a stability against buckling that cannot be achieved with conventional compression springs.

Many applications require two similar springs, but with one right-hand coiled and one left-hand coiled. In some cases, these two springs can be combined into a double spring, which has one right and one left-hand coiled spring body connected to each other.

Torsion bar springs is a good alternative to clock springs or helical torsion springs, when a rotational torque is needed in applications where the spring shall fit into a space that is limited radially, but with lots of space axially.

Most common ends are different types of end loops and hooks, there are also a wide range of other mechanical attachment possibilities such as coiled in and screwed in attachments. Examples are, half hooks, German loops, English loops, extended hooks, side hooks, side loops, screw plugs and screw shackles.

A snap or retaining ring is a fastener or retaining ring that consists of a semi-flexible metal ring with open ends that can be snapped into place. It fits in a groove on a shaft or inside a bore and locates the shaft axially in one direction.

The number of turns is individually determined and can be as much as 50. Different coiling techniques exist to give the material the desired curvature that matches the torque-rotation requirements. The spring has many similarities with clock springs, but have a much larger operating range in terms of number of turns.

A Garter Spring is a circular ring made from a coiled helical spring bent into a circle and with the two ends connected to each other. A garter spring will create a radial force directed towards its center when the radius of the garter spring increases.

Disc springs (also called Belleville springs) are geometrically a cylindrical washer with a slightly conical shape. It is used as compression spring and is the best solution when forces are high and travel relatively limited. This type of springs can or in parallel, which increases travel and/or force.

Constant Force Springs are manufactured from flat strip material and spooled to a specific curvature matching the needed pull force. There is practically no limit on extension speed and acceleration. The springs can be fitted in a number of ways and extended partly or completely.

Compression springs is the most common type of springs. The majority of compression springs are cylindrical and linear, but to this group belongs also conical, barrel shaped, tapered out ends and more. The design can be adjusted to fulfill a wide range of requirements concerning spring characteristic.

Clock Springs – also called hair springs – is a torsion spring that is optimum for installation spaces that are limited axially, but with more space radially. They are made from strip material or flat rolled wire that is wound in a flat, spiral shape.

Stampings (and stamped parts) are versatile and you find them in a wide range of applications for many different industries. Lesjöfors delivers stamped parts from our standard program as well as customized solutions.

Flat springs are parts made of strip material where the material is stressed in the bending process and the relation between deflection and force is a vital part of the function. Their design can be varied extensively to fulfill both load-deflection and assembly requirements.

Lesjöfors manufactures deep drawn parts to customers individual requirement in press machines by either progressive tool or transfer tool solutions as well as opportunities for less automated solutions in case of low volume requirement.

Circlips and Locking Rings consist of a semi-flexible metal ring with open ends that can be snapped into place. They fit in a groove on a shaft or inside a bore and locates the shaft axially in one direction.

Wave Washers are washers with a wave form and gives an axial force when the waves are flattened out during compression. The function is similar to wave springs, but wave washers have only one coil

We manufacture stamped/bent parts to customers’ individual requirements in our multislide bending machines. With a high technical expertise, cost-effective manufacturing and an effective service we serve our customers all over the world.

Stainless steel gas springs function the same as their common hydraulic counterparts, but give an alternative when operating under rough conditions such as off-shore and other outdoor exposure applications. Other commons application areas for stainless steel gas spring include health care products, food industry and medical devices.

Dynamically dampened gas springs are commonly used in applications that do not allow the piston rod to be facing downward in the open position, while maintaining the ability for soft and controlled damping.

Lockable gas springs are commonly used in applications requiring the ability to lock out the stroke in a desired position without the need for external locking mechanisms. This is achieved by a unique piston design that separates the gas and oil chambers of the spring

Traction gas springs differ from conventional gas springs in that they operate in the pull direction rather than pushing out with force. In the unloaded state, the spring is compressed with the piston rod inside the cylinder.

Typical areas of use for hydraulic gas spring are controlled opening and closing of hatches and hoods. The gas springs can also be adapted to control complete equipment such as ventilation apertures, chairs, beds, windows, tools and machinery.
