When selecting an O-ring for a hydraulic cylinder or other component, it is important to understand the type of motion that will occur in the area to be sealed. As author Xing Hong from WRKR Seal explains in our top story in today’s newsletter, the type of motion occurring impacts seal design limits and gland specifications such as squeeze, groove location and installed stretch.

Depending on the type of motion, typically either a rotary or reciprocating seal is used. Hong offers his industry expertise on how design limits and gland specifications differ between these two seal types so you can better determine which may be the better fit for your application needs.
