Belleville or 'spring washers' are cone-shaped spring discs and are used singly or in stacks to achieve a desired load and travel. In general, they function best under conditions requiring very high load in confined space or short travel. Under these constraints, it is often not practical or even possible to use a coil spring.

Designed to maintain load tension in light bolted assemblies, where a constant load is required, Rolex AI Series Springs are typically manufactured from High Carbon or Alloy steel; AISI C1075 or 6150 material. Disc springs exert a uniform pressure that remains constant despite tension losses caused by thermal expansion, contraction, compression set or wear of parts. (read more)
