Smalley Steel Ring Company

About Us


In 1918, Smalley was founded as a supplier of precision automotive piston rings. Today, Smalley Steel Ring Company is the market leader in the industrial retaining ring, snap ring, wave spring and compression spring business, a position we work hard to maintain and build upon. Located in the Midwestern region of the United States, Smalley's offices and manufacturing facility are in Lake Zurich, Illinois, a northwest suburb of Chicago.

Every Smalley retaining ring and wave spring is engineered and manufactured to the highest quality standards using skills and processes we have honed over three-quarters of a century. Our obsession with quality, combined with our near-perfect record of on-time delivery, has earned us an approved supplier status with leading OEM manufacturers around the world. Due to the ceaseless demands we place upon ourselves, Smalley has won the coveted title of Preferred Source in the most demanding retaining ring and wave spring applications: automotive, agriculture, aerospace, electronics, appliance, and industrial.

While we are understandably proud of the recognition we have received, ultimately, it is our products that set us apart. Unlike stamped rings and springs, which are stamped through the metal grain, our edgewound retaining rings and wave springs have a circumferential metal grain structure that gives them exceptional strength, dimensional stability, and predictable performance characteristics.

Finally, every Smalley snap ring and wave spring is backed by our continued support. We are constantly researching ways to expand and improve our Customer Service and Engineering/Technical Assistance. We welcome your comments and your design challenges. Smalley will work hard to become your Preferred Source of retaining rings and wave springs.
