Wave washers divided into WG type, WL type, WN type
3. Disc spring washer
Disc spring washer Belleville spring washer, also known as Belleville French. HDS Series is a very effective bearing load and elastic recovery. Bolt tension can withstand slack due to wear, creep, relaxation, thermal expansion, shrinkage, or seal compression of the consumable parts. The HDS series multiples the elasticity of the screw several times, effectively replacing conventional spring washers, but not suitable for locking washers and flat washers.
