Disc springs made from polymers are an innovative new addition to the igus product range. igus polysorb disc springs are said to be space efficient and especially suited for a wide range of manufacturing industries where product designs necessitate a short spring length.

Design benefits and advantages claimed of igus non-magnetic polysorb disc springs include improved linear spring characteristics compared with metal alternatives and elimination of running tolerance and end float. They absorb vibration, reduce noise and give electrical and thermal isolation. Polysorb disc springs are also corrosion resistant, require no lubrication and are of low weight and effectively reduce space requirements.

In many applications several disc springs are combined alternately as a stack of springs to increase spring travel. Spring travel increases in proportion to the number of springs used, while the spring force remains the same as that of a single spring. To further increase spring force, the disc springs are stacked in parallel, as a package of springs.

Cost-effective and said to have proven reliability, igus polysorb disc springs are said to be resistant to mild alkalis, acids, fuels and lubricants. Absorption is very low and therefore they are ideal for use in a wet or humid environment.

igus polysorb disc springs reportedly can be used in a temperature up to 80°C and still have a spring force of 8N. In the event of being used for long periods in submerged conditions, they can show a spring force of 10N.
