Polyurethane and Rubber Elastomer Springs

Elastomers are designed to absorb forces, they absorb impact forces aswell as continous forces.

Elastomers can be used to substitute helical springs aswell as for energy absorption or damping in multiple applications.

The main contrast between these and steel springs is that the elastomers are more reliable in emergency situations because of their longer life being unattended. Elastomers have a maximum load resistance aswell as an excelent impact absorption capacity

Our elastomers have a high resistance to oil, cracking and heat. Their capacity to withstand heat is a minimum of a constant 80ºC temperature. all standard pieces are based on DIN 9835 standards.


We have two standardized sizes with standard market measures. These elastomers, also known as rubber and polyurethane cylinders, present/display a series of measures, with two different hardness's', to cover the most common necessities:

rubber springSerie SZ 8500: Material used for production: Chloroprene (CR). Final hardness: 70 +/- 3 Shore A. These are known as rubber spring.

polyurethane springSerie SZ 8590: Material used for production: VULKOLAN. Final hardness: 90 +/- 5 Shore A. These are known as polyurethane spring.

There are other normalised products. To obtain more information ask us.


We also offer special sizes with different hardnesses. This type of pieces are usually designed to absorb energy in small strokes to improve the life span of equipement or machinery, exposed to vibrations.

We can recommend the elastomer which most suits each customer, which best adapts to the usage conditions with a goal to obtain a stable performace within long periods of time even under harsh conditions.

If the materials and characteristics of the are not chosen appropriately performance can decrease in a very short period of time, that's why its best to be advised on what to purchase.

Contact our technicians and they will advise you in the best way.
