Smalley Wave Springs: Gap and Overlap

Smalley Single Turn Wave Spring

Single turn wave springs are used in a wide variety of applications. They function with precision and dependability, especially in applications with short deflections and low-to-medium forces.

There are two basic types of single turn wave spring: the gap type and the overlap type. Just as the names would imply, the gap type is split to retain a gap between the ends, while the overlap type has overlapping ends.  Both types of permit the radial expansion in diameter within a cavity without the binding or hang-up normally associated with die-stamped wave washers. The ends of both types are free to move circumferentially as the spring outside diameter grows during compression.

For example, the O.D. of a gap wave spring would fit .020 loose per side in a bore which is to say  that the I.D. clears a shaft by .010 per side. As the spring is deflcted, the O.D. and I.D. grow larger until the O.D. contacts the bore. Continued deflection causes the gap ends to move closer together while the O.D. presses against the bore. An overlap wave spring permits this type of cycling action in a similar manner.

Series Description (Click a Row for Detailed Specifications)
SSR PDF Icon Single Turn, Standard Gap and Overlap
Single turn gap or overlap type wave springs can be ordered from stock and are suitable for a majority of applications. Choose from a large selection of bore and rod diameters, loading capacities, work and free heights, number of waves and thicknesses.  Standard parts available in both carbon and stainless steel from 1/2" to 16".
SSR-N PDF Icon Single Turn, Narrow Section, Gap and Overlap
Available in carbon and stainless steel from 3.250" to 7.750" diameters. Originally designed to pre-load packings in telescoping hydraulic cylinders, they are also found in other applications where working space is highly limited. Designed to fit into a bore with a light snap to assure perfect concentricity between the wave spring and assembly. When compressed, radial expansion is taken up by the gap in the spring to eliminate binding.
