For nearly 50 years, Borrelly Spring Washers, designer and manufacturer of technical spring washers, has always been able to adapt to new technologies to create innovative solutions. The Belleville Carbon Spring Washer proves that we are still delivering top-notch products.
"We are the first in France and Europe to have developed a spring washer in composite material," says Fabien Bourgeon, in-house engineer.
Made to measure, the washer has been designed to meet the customer's needs. Diameters can range from 10 mm to 150 mm. Using these washers procures multiple advantages.
To begin, Carbon is lighter; weight savings can be made. In fact, carbon washers are 60% to 70% lighter than their equivalents in metal washers. That makes these washers ideal for sectors such as aerospace, military and motor sports. These tapered washers develop the most force for a given volume, and they can be stacked. These new Belleville washers also offer high chemical resistance to acids, alcohols, oils and salt solutions, unlike steel (or even stainless steel) washers. This feature makes them particularly suitable for use in the medical and food industries.
Lastly, their material is non-magnetic. This feature marks them out as a potential alternative to non-magnetic metallic solutions, which are very expensive and used in the design of small electric motors.
