(36) Perhaps the most popular and widely used radial retaining ring is the "E" (so named because it is shaped like the letter "E".) Three prongs make contact with the bottom of the groove and provide a shoulder for effective retention of assemblies.
(11) The RE retaining ring is a reinforced version of the E ring. which will accommodate higher thrust loadings and RPM. RE rings function in the same groove as regular E rings. so that you can change from one to the other without re-engineering the application.
(33) The LC ring is produced in two identical halves. The ends interlock into a groove on a shaft and. once assembled. are dynamically balanced. As a result. they are particularly effective at retaining assemblies with extremely high rotational speeds.
(24) The PO ring features wide "ears" (resembling those of a poodle dog. thus the name) which offer extra retention surface against the retained part. PO rings also come in thinner sizes as a standard series of rings known as POL.
