Other names: Rubber spring, Polyurethane spring, Pu spring, etc…
A Polyurethane spring is a spring made of polyurethane. It has the following characteristics:
– Good vibration damping effect: Polyurethane spring has better vibration damping effect, small resonance field, long service life, low cost, good cold resistance and excellent air-tightness.
– Large elastic deformation:Polyurethane spring modulus of elasticity is small, there is a large elastic deformation after being loaded, to absorb shock and vibration. It can be subjected to multi-directional load at the same time, in the machinery industry, the vibration damping effect is very obvious.
– High internal resistance: the internal friction damping of Polyurethane springs is larger than that of metal springs, so it is better for the absorption of sudden shocks and high-frequency vibrations, and has better sound insulation properties.
– Compact structure: Polyurethane springs can be made into a variety of different shapes and sizes of products, the structure is very compact, and can make effective use of space.
– Easy to install and dismantle:Polyurethane springs are easy to install and dismantle without lubrication, which is conducive to maintenance.
In the selection of Polyurethane springs, you need to consider its shape, stiffness, load-bearing capacity and other factors, and according to the specific requirements of the use of choice.
Choosing for Polyurethane wheels can reduce maintenance and OEM product cost. It provides a cut down in maintenance time and failure costs while you gain the advantages of optimal rolling resistance
