U-Spring
The NPI U-Spring is a cantilever beam geometry made from stainless steel or other alloys and is applied as a radial or axial compression energizer inside of U-Cup type seals. The U-Shape provides a moderate load / deflection range and is used in dynamic and static applications. The U-spring is available in four standard sizes and can be ordered by the foot or cut and welded to specific diameters. Custom sizes and materials are also available.
