FEY rings are an effective sealing solution in many different applications. Because the FEY rings are precision engineered components, the following technical pages provide general design guidelines as for proper use of the FEY sealing and retaining rings. This will help to maximize the sealing or retaining effect in an application’s environment. If your application has special design consideration, please contact us using our application data sheet.

Machining of Components
FEY rings are designed to be used in combination with a ring carrier and the shaft or bore that it is being sealed against. Here you will find general guidelines for design and fabrication of the FEY ring's mating components.


Like many other parts, improper installation can lead to sub-standard performance. The same is true for FEY rings. In this section you will find helpful tips for manual and tool-assisted installation.


Although FEY rings can be run dry, these seals benefit greatly by using proper lubrication methods. On this page, you will find proven design suggestions that can aid in lubricating the FEY sealing rings.


Many companies that use the FEY sealing solution have very active quality control programs. Located on this page you will find the tolerances for the standard FEY ring width (RD) and radial wall thickness (RB) as well as the machined shaft/bore tolerance that should be maintained.
