SSR-N Series

Narrow Section Wave Springs
Smalley narrow section wave springs were originally designed to pre-load packings in telescoping hydraulic cylinders. They have also
found other applications where working space is highly limited. This Smalley Wave Spring series is designed to fit into a bore with a light
snap to assure perfect concentricity between the wave spring and assembly. When these narrow section wave springs are compressed,
radial expansion is taken up by the gap in the spring to eliminate binding.
Stock Items in carbon steel and 17-7 PH stainless steel. Springs listed below are 4 waves and up, Gap Type.
