Bowed Retaining Rings

Check out our full Bowed Retaining Rings Spec Chart below.

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.

Other internal rings we offer include Standard Retaining Rings, Beveled Retaining Rings, Push-On Retaining Rings and Balanced Lug.
