The Smalley SSB-0551 wave spring is a single-turn gap type spring made from SAE 1070-90 carbon steel with an oil-dipped finish. It fits a bore diameter of 140 mm and clears a shaft diameter of 126.38 mm, providing a load capacity of 382.7 N at a working height of 3.18 mm. The spring features six waves with a thickness of approximately 0.76 mm, designed for precise force application in compact radial spaces. Its dimensions and material properties make it suitable for applications requiring consistent load and space-saving spring solutions, such as pressure relief valves and clutch drives.
