Wave Washer with Gap

Wave spring washers provide medium loads in a small axial space. This series is split, in other words there is a small gap in the wave circumference. This gap or split allows the ends to move during compression, which if constrained in a bore prevents binding. Common applications for this type of parts is adjacent to ball bearings, where shaft take up or thermal expansion & contraction accommodation is required. The gap or split is advantageous for such applications where the bore is made of softer material than the spring.
