Bowed External Retaining Rings

tax-term-featured-image

Bowed retaining rings act as a spring once they are properly installed into a groove. This main benefit allows the bowed retaining rings to compensate for accumulated tolerances. Generally when parts are manufactured, it is difficult to make them to exact precise dimensions. Bowed rings help to 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 external retaining rings we offer include Standard, Bowed, Heavy Duty Push-On, Heavy Duty Standard and Grip.

See below for our entire list of external bowed ring dimensions and configuration drawings.  If you do not see a ring that meets your specs, you can custom-design your own external bowed ring right on our site!
