A great alternative to stamped retaining rings

Arcon Ring’s closed and open round wire snap rings are known internationally for their ability to hold tight tolerances, providing a great alternative to (lug-style) stamped retaining rings. We provide short, fast lead times because our open and closed round snap rings require no extensive tooling, which traditionally lengthen lead times. Closed and open round wire snap rings are both used for shaft applications, while open gap rings are primarily used for internal bore compression applications. Let Arcon Ring help your business stay cost-effective and boost your productivity and efficiency.

Customizable Solutions

Arcon Ring offers customizable gap configurations for our open and closed round wire rings. If you don’t see the exact configuration below to meet your needs, visit our Design Your Own Snap Ring section.
