The 48-inch Urethane Compression Spring is an exceptional solution for applications where corrosion, vibration, and magnetism restrict the use of traditional steel springs. With a hardness of 95A duro and a high-load carrying capability, this spring offers reliable performance in punching, stamping, and drawing dies. Its abrasion resistance, non-magnetic properties, and oil/solvent resistance make it a durable and long-lasting choice. Additionally, its effectiveness in temperatures ranging from -30°F to 180°F, vibration damping qualities, and shock absorbance further enhance its utility in various engineering applications.

Specifications Additional Information

Because of the exceptional load bearing capacity of urethane compression springs in the shape of tubes, cylinders, rectangular pads & sheets, urethane compression springs are used very successfully in various Engineering applications such as seismic bridge bearing blocks. Urethane compression springs and bearings also outperform rubber in terms of load bearing capacity, abrasion resistance and resistance to ground level ozone. One of the problems with rubber materials is their susceptibility to liquids and ground level ozone produced by the increasing number of automobiles or by electrical discharges. Over time rubber gradually cracks and deteriorates due to exposure to liquids and ozone. Polyurethane, however, is far more resistant to liquid and ozone attack. In fact, testing shows that polyurethane can be exposed to at least five times longer to the high levels of ozone specified for rubber in chapter 18 of the AREA manual (ASTM D1149) without deteriorative effects. P.P.CâS urethane spring material is 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 incresing the diameter by the same amount of compression. Example: A 2.00-inch long spring is to be deflected 15% or .30 inches. The diameter will then also increase approximately by .30 inches. This materialâs lateral expansion must be considered for many applications, especially when they have to fit inside cavities. The recomended maximum free (unloaded) length is 2-1/2 timeâs the spring out side diameter, although springs may be stacked with guide rods and washer-shaped spacers, for taller applications.
