124.97mm Outer Diameter Disc Spring

Cat spring parts come in a variety of strengths and sizes to fit specific applications. Compression springs are helical designed springs for compression and tension whereby the spring gets compressed (shorter) as more weight is applied. Machine hooks are made from the end coils of the spring by bending the end of the wire out to create the hook or loop. Crossover hooks are made from the end coils of the spring but are bent straight down the center of the spring first before then bending the wire out to create the hook or loop. This is a more stable hook than the machine hook.
