Belleville Washers, also known as disc spring washers, are conical-shaped fastening components designed to provide high spring force and load capacity in bolted assemblies. Their unique conical design allows them to compress under load and exert continuous pressure, helping to maintain tightness and prevent loosening caused by vibration, shock, or thermal expansion.These washers are manufactured from premium quality spring steel, stainless steel, carbon steel, or alloy steel, ensuring excellent strength, durability, and corrosion resistance. Belleville washers can be used individually or stacked in series or parallel to achieve different load and deflection requirements.
