What is the difference between friction shims and spring washers? Can DAOLER completely replace them?
In the field of mechanical anti-loosening, spring washers are widely used due to their low cost. However, under high-vibration or heavy-load conditions, their anti-loosening performance often proves inadequate. Spring washers rely primarily on elastic force to provide axial preload; nevertheless, under long-term alternating stress, the elastic force tends to degrade significantly or even result in fracture, ultimately leading to joint failure.
In contrast, DAOLER diamond friction shims operate on the principle of "friction-driven torque transmission." The diamond particles embedded on their surface create a microscopic mechanical interlock with the mating surfaces, generating a substantial frictional torque when subjected to load. This mechanism fundamentally suppresses relative slippage at the joint interface.
For high-reliability, high-torque-transmission-efficiency applications in premium equipment—such as wind power systems, robotic joints, and aerospace structures—DAOLER anti-loosening shims serve as a perfect substitute for conventional spring washers. Not only do they deliver an exponential improvement in anti-loosening performance, but their high-friction design also enables a reduction in the number of fasteners required, contributing to lightweight construction.
That said, for conventional civil applications involving minimal load and negligible vibration, spring washers may still serve as a cost-effective baseline choice, provided that cost remains the primary consideration.
