Bowed Internal Retaining Rings

Internal Retaining Rings: Bowed

Bowed retaining rings act as a spring once they are properly installed into a groove. Generally when parts are manufactured, it is difficult to make them to exact precise dimensions. Bowed retaining rings help correct the “play” that occurs on the shaft by acting as a spring that keeps compression.

Arcon Ring offers the best and most reliable bowed retaining rings in the industry. We can accommodate most every size to your exact specifications.

See below for our complete list of bowed retaining ring dimensions and configuration drawings. If you don’t find the specs you need, you can custom-design your own bowed retaining ring right on our site. We also offer other internal retaining ring options, including Standard Retaining Rings, Beveled Retaining Rings, Push-On, and Balanced Lug.
