Lee Spring Company Belleville Washer 625-062-1375

When your compression spring application requires a high load in a small space, Lee Spring’s Belleville Washers can be the solution. 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 Belleville 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
