Sealing ElementsTechnical Handbook O-rings3. O-ring Applications Dynamic Applications:There are three varieties of dynamic applicationsas noted below:Piston seal1. ReciprocatingReciprocating seals refer to seals used in applicationsthat slide back and forth. This motionintroduces friction, which creates design considerationsdifferent from those of static seals.The O-ring may be housed in a groove (rodseal) in the cylinder wall instead of a groovein the piston surface (piston seal) without anychange in design limitations or seal performance.See figure 1-14. Fig. 1-14Rod seal2. OscillatingOscillating applications are thoseseeing both rotary and reciprocating movement.A valve spindle is an example of an oscillatingapplication. See figure 1-15.Fig. 1-15 3. RotaryRotary seals refer to seals used in applicationsthat rotate. See figure 1-16.fig 1-17Fig. 1-16Miscellaneous ApplicationsO-rings are used in a variety of applications.Wipers, buffers, and drive belt applications arejust some of the examples.
