Urethane Springs

Urethane compression springs are generally used in environments where steel wire springs are not well suited. For example, these springs are useful in applications where corrosion, vibration, and magnetism prevent the use of conventional steel springs. Urethane springs are also proven to be the safest, most efficient, and reliable compression material for punching, stamping, and drawing dies.

  • Urethane Springs Characteristics

    Our urethane springs are produced from a polyether-elastomer that reacts similarly to an incompressible fluid. The volume of material moved by compression is displaced laterally in the form of bulging sides. An approximation to the change in diameter of one of our standard cylindrical urethane springs can be made by increasing the diameter by the inches of compression.

    Example: A 1.00″ long spring is to be deflected 15%, or .15″. The diameter will then also increase roughly by .15″. This material’s lateral expansion much be considered for many applications.

    The recommended maximum free (unloaded) length is 2 1/2 times the spring’s outside diameter, although springs may be stacked with guide rods and washer-shaped spacers.

  • Benefits of Urethane Springs

    Urethane springs offer multiple advantages over conventional springs:

    • High load-carrying capability
    • High dielectric strength and non-magnetic
    • Protection against marring/galling
    • Longer life
    • Abrasion resistance
    • Oil and solvent resistance
    • Low noise
    • Vibration damping and shock absorbance
    • 100% load-bearing surface
    • Bondable to mating parts
    • Effectiveness between -30° F and 180° F
