DIN 2093 washers, also known as Belleville washers or disc springs, are conical washers designed to generate high compressive forces in a small axial space. Their elastic behaviour allows the joint tension to be maintained even when there is settlement, vibration or thermal changes.
They are used in critical bolted joints, flanges, heavy machinery, prestressing systems and assemblies where it is necessary to ensure a constant level of preload on the bolt to guarantee its long-term stability.
DIN 2093 Belleville washers: high preload in a small space
DIN 2093 Belleville washers are used in systems where precise preload values must be maintained, such as flanges, valves, compressors and technical machinery joints. Their conical design provides a predictable load curve and allows them to work individually or in combined packs to adjust the required force and deflection. Their ability to absorb stress variations and maintain clamping load makes them an effective solution in critical assemblies that must maintain mechanical performance throughout the service life of the assembly.
