- Key Products/Technologies
- Smalley's primary product lines include Spirolox® Retaining Rings, Constant Section Rings, and Wave Springs. Spirolox Retaining Rings provide a 360-degree retaining surface without protruding ears, minimizing assembly interference. Constant Section Rings are suitable for heavy-duty or impact loads, featuring a uniform cross-section for excellent load distribution. Wave Springs offer up to 50% space savings compared to conventional coil springs while delivering equivalent force and deflection.Smalley's primary product lines include Spirolox® Retaining Rings, Constant Section Rings, and Wave Springs.
