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
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.

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".
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.
Single Turn, Metric Bearing Preload, Gap and Overlap
Available in both carbon and stainless steel
from 16 mm to 600 mm diameters. Designed to match
popular metric bearing sizes.
