H-13 Tool Steel Belleville Washers
Belleville washers are unique, conical shaped washers recommended for use in applications where high vibration, differential thermal expansion, relaxation, and/or problematic bolt creeping are of concern. Their conical shape affords a high spring rate over a short deflection to retain the proper bolting stress. Stacking Belleville washers in different configurations allows for the spring rate to remain more uniform over a larger deflection, or can increase the spring rate, depending on the method of stacking.
Belleville washers are available in a wide range of materials including, but not limited to, Carbon Steel, 301 Stainless Steel, 17-7PH Stainless Steel, H-13 Tool Steel, Inconel 718, and Phosphor Bronze.
