Associated Spring RAYMOND 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. Applications with AQL requirements should contact ASR Engineering. Standard parts are available in stainless steel and carbon steel. Common applications for this type of parts is adjacent to ball bearings, where shaft take up or thermal expansion and contraction accommodation is required. The gap or split is advantageous for such applications where the bore is made of softer material than the spring.
