General Description of Urethane Spring FOR HIGH LOAD Application Example Optimum for pad pressure of press tools Urethane spring USA and USX for press tools use polyester based cast For operation with single stage spring urethane elastomer which is heat resistant. It is excellent in repeated Shoulder Bolt compression. It also has high impact Stepped Bushing resilience, impact resistance, weather resistance and load resistance. It is the source of press tools. Pressure Source Components optimum product for pad pressure Features (1) Since material is hard and elastic, it is excellent in impact resistance and shows a strong performance as a spring. Physical Properties (2) Since it is excellent in oil resistance, weather resistance and aging resistance, the service life is long. (3) Additional cutting and grinding can be made with ease. Physical Property Values Radius (Refer to the radius in the detailed drawing for non-machined surface.) For operation with double stage spring Detailed Drawing of Radius Navy blue Tensile Strength Impact Resilience (4) Shape is a thick wall round pipe and is easy to handle.
