CDM Series Belleville Washers CDM Series »

Century Spring Corp. disc spring fabrication is subject to exacting manufacturing and quality control standards. The high carbon C1075 or alloy AISI 6150 materials used are generally in annealed condition and hardened to within a range of Rc 44-51 depending on material thickness. All discs are preset so that they will not significantly relax under load over time. Browse Products »



CDS Series Belleville Washer CDS Series »

In addition to classic Belleville washers, we also offer a line of pre-stressed disc springs specifically sized for use with bolts. The primary function of our CDS line is to create a constant bolt load in bolted assemblies. Load compensation for differential expansion due to heat or dissimilar metals, such as electrical connection bolting, or in wear situations, or when "torque-setting" is required are good examples of CDS Belleville washer applications.
