Abstract

A length of canted coil spring is disclosed which is suitable for forming a stable, when unsupported, circular axially loadable spring. The length of spring includes a plurality of elliptical coils canted along a coil centerline with the coil centerline following a helical path about a helix centerline. The length of canted coil springs is approximately equal to a distance, or pitch, along the helix centerline necessary for one complete revolution of the helical path thereabout.
