Custom made

Thanks to our experience and know-how, our in-house design office can solve the most demanding problems in high-tech sectors, from prototype to mass production.

Borrelly Wave Washers

Created and developed by the Borrelly family, mainly used to take up internal play to reduce vibration and increase bearing life.

Borrelly Ondufil® Wave Springs

Products capable of restoring loads equivalent to a coil spring in a considerably reduced axial space.

Borrelly Belleville Disc Springs

Stacking enables high loads and a wide range of yield curves.

Borrelly Diaphragm Washers

These springs gain force when they expand, not when they compress.

Borrelly ROB® : Optimized Belleville Disc Spring

Similar to the Belleville, the ROB® washer offers considerable weight savings.

Borrelly Ribbon Springs

Used in conjunction with our other products, they control the clearance between the bearing and its housing.

Borrelly 360 Spiral Retaining Rings
