Elastomer Springs Type Urelast 90, DIN 9835 PUR

Advantages over steel springs include break resistance and material damping. Tool damage due to fatigued or broken steel springs is eliminated. With proper application, a lifespan greater than 2 x 10^6 load cycles is easily achievable. Temperature range: –20 °C to +80 °C. Made from tempered polyurethane rubber (PUR), dynamically highly loadable, red. Specified values for maximum load: approx. 30 % (factor 1.3). Hardness according to DIN 53 505: 92 Shore A. Tensile strength according to DIN 53 504: ≥ 40 N/mm². Elongation at break according to DIN 53 504: ≥ 550 %. Tear resistance according to DIN 53 507: ≥ 50 N/mm. Rebound elasticity according to DIN 53 512: 43 %. Abrasion according to DIN 53 516: ≤ 40 mm³. Compression set according to DIN 53 517 (24 h/70 °C): ≤ 20 – 30 %. Bulk density according to DIN 53 479: 1.27 g/cm³. Spring travel (s): 30 %. Settling tendency (Ss): 5–8 %.

Note: These values refer to the original height of the springs and apply to high dynamic loads depending on the stroke frequency. To ensure a force-fitting spring application regarding settling tendency and pre-tensioning, a force specification compensates for the initial force drop. Installation requires clearances or distances for the springs to expand in relation to the percentage deformation. Guide pins (DIN 9385) are used for guidance and centering; they are essential for spring columns and slender individual springs.
