Ask Smalley. We have nothing against sales people. But when it comes to differentiating Inconel from Elgiloy or overcoming dimensional variations within a complex assembly, wouldn’t you rather work with an engineer? Our customers would. That’s why they collaborate directly with our world-class team of Smalley engineers—experienced professionals whose only focus is helping you specify or design the ideal wave spring, Spirolox® retaining ring or constant section ring for your precision application. Smalley wave springs reduce spring operating height by 50%, saving space and weight, axial spaces. We offer more than 4,000 stock sizes in carbon and stainless steel.
