Borrelly Ondufil Wave Springs
Compared to helical springs, Ondufil Wave Springs can handle the same loads but require less axial space to do so.
Thanks to this gain in axial space, the number of mechanisms of an assembly can be reduced significantly.
If a Borrelly wave washer is not delivering sufficient deflection, the Ondufil Wave Springs, by optimizing the number of active wave turns, gives a solution that is superior to a helical spring.

Technical description
An Ondufil wave spring is a round elastic element taken from the same family as our Belleville or Diaphragm washers, resulting from a new manufacturing technology consisting in simultaneously rolling and corrugating a flat wire corresponding to the width of the coil.
Ondufil wave springs meet ever-increasing customer needs for more compact housings, greater deflections (as regards elastic deformation) and a greater variation in terms of spring rates.
Our Engineering & Design Department, using powerful calculation software, can respond quickly to your needs.
Our production workshop, fully integrated with production equipment designed and developed by Borrelly, can produce Ondufil wave springs from prototypes to very large runs.
Borrelly Ondufil single-turn gap type : the Ondufil wave spring can be centred in a bore (even allowing a slight tightening).
.
Borrelly Ondufil multi-turn wave springs with shim ends :multiply the deflection of a wavy turn by the number of turns. If shim ends are used, support rings are no longer required.
The open coil of a single-turn Borrelly Ondufil wave spring, of gap or overlap type, allows us to centre the washer along the bore (even allowing a slight tightening). Its diameters do not vary regardless of the crushing height.
In the case of a Borrelly Ondufil wave spring with several inverted or overlapping turns, centring can be done either along the shaft or bore. Please consult us for the clearances to be provided during assembly.
