Our high-precision, durable guide units are designed for universal use in the fields of toolmaking, machine engineering, measuring device design and apparatus engineering.
System springs
– a wide variety to suit every application
High flexibility and a wide force spectrum
System springs from STEINEL are available in different diameters and lengths, all in up to eight load types. As a result, we have the optimum system spring for every application and force requirement.


Types of load are colour-marked so that they can be immediately told apart.
They all have standardised installation dimensions, which means that it is easy to increase or reduce the level of compressive force even at a later date.
- All springs are made of alloyed valve spring steel (CrV/CRSi). This wire is especially resistant to impact and vibration stress and can be used at operating temperatures of up to 180 °C.
- The high-quality material enables system springs such as the BLACK SZ 8047 to exert forces of 2,000 daN at maximum stroke. The BLACK SZ 8049 exerts a force as high as 2,500 daN, making it stronger than some nitrogen cylinders.
As STEINEL also provides all components for pre-loaded spring units in addition to system springs, you can always rest assured that your systems will be perfectly coordinated and ready to install.
