External Retaining Rings: Bowed External Retaining Rings

Arcon Ring’s Bowed External Retaining Rings are designed to act as a spring once installed, helping to compensate for accumulated manufacturing tolerances. By maintaining constant compression, bowed rings reduce shaft “play” and ensure a more secure fit. Ideal for applications where dimensional variation is a factor, these rings provide reliable performance and lasting tension.
