Dynamic Rotary Gland Design

In a dynamic rotary seal applications a turning shaft protrudes through the I.D. of an o-ring, the o-ring then becoming a seal. The table below lists recommended dimensions for dynamic rotary seal glands by AS-568A o-ring dash numbers. There are a number of factors that should be carefully considered when designing the gland for a dynamic rotary o-ring application. The table below provides a standard set of guidelines to assist you in your design.

-The elastomer selection should directly correlate with the type of application in which the o-ring seal will be used. You can review our materials/elastomer section to examine the primary qualities of the material type under consideration.

Dynamic Rotary Gland Seal Diagram
Due to the number of interacting forces, it is STRONGLY RECOMMENDED THAT YOUR ELASTOMER SELECTION BE RIGOROUSLY TESTED IN THE ACTUAL APPLICATION, performance assumptions must be checked so that you are certain that all variables have been carefully considered.
