Their conical configuration enables them to support high loads with relatively small deflections and solid heights compared to helical springs. Belleville Washer are often used to solve vibration, thermal expansion, relaxation and bolt creep problems. Lee Spring Belleville Washers are manufactured from 300 Series Stainless Steel. This alloy offers good corrosion resistance for most applications. Additionally, Lee Spring Washers are passivated in accordance with specification ASTM A967 (supercedes QQ-P-35) to remove contaminants and further improve resistance to corrosion. 300 Series Stainless Steel is slightly magnetic and is recommended for any applications where the temperature is below 500° F(260° C). Additional load flexibility can be achieved by stacking Belleville Washers in various configurations. As shown in the diagrams below, Belleville Washers can be used in four different ways: Single: One washer Parallel: All washers stacked the same way Series: All washers stacked opposite each other Series-Parallel: A combination of the two A single Belleville Spring Washer has a specific load for a given deflection. Two washers stacked in parallel will yield double the load of a single washer for the same deflection;three washers will yield triple the load; four washers will yield four times the load, etc. Alternatively, two washers stacked in series will yield double the deflection of a single washer for the same load; three washers will yield triple the deflection; four washers will yield four times the deflection, etc.Various series-parallel combinations therefore can provide a wide variety of combined results of load versus deflection for the stack. Consequently, depending upon the application, the designer can:
