BORRELLY SPRING WASHERS
Spring washer manufacturer, BORRELLY SPRING WASHERS SARL has specialised since 1970's in developing, designing and manufacturing .
BORRELLY SPRING WASHERS SARL analyses and develops high quality precision spring washers : belleville washer, wave spring washer, spring rings, steel washers...Directly involved during the design phase, BORRELLY is recognised by the most important companies in the fields of aeronautics, aerospace, Formula 1, nuclear industry whilst not forgetting automobiles and industrial valves. Each manufacturing phase for a spring washer is completely done in the company factories (design and production of tooling, cutting, stamping, heat treatments).
Spring washer advantages
Spring washer is a type of spring and have a wide range of mechanical applications. Compared to a compression spring using round wire (quite high compared to its diameter), the spring washer (quite flat compared to its diameter) saves space and weight. A spring washer is used therefore when a round spring is required in an element and there is space available in terms of diameter but not in terms of height. Furthermore, in a standard spring, the material is only compressed in torsion, which implies that force is always proportional to displacement (except if complex methods such as non-cylindrical windings, varied winding spacing or variable diameter wire are used).The same does not apply to spring washer which, being flat springs, can use flexion, torsion and shear compression. By combining different compression types as the deformation varies, the forces obtained do not need to be proportional to displacement, enabling the elasticity curve to vary to achieve the desired force.
Utilization of spring washer
Borrelly produced numerous kind of spring washers : ONDUFIL® rolled and wave washers, Belleville spring washers, Diaphragm spring washers, thin shims, rings for bearing ball,…
Borrelly will help you design the best spring washer for your needs.
