Radially Assembled
Retaining Ring Radially Assembled retaining rings are radially installed into machined grooves on shafts. They don’t have lugs or lug holes and do not extend as far around the circumference of the grooves as their axial counterparts. Consequently, they can be installed quickly using Rotor Clip applicators and dispensers. Rotor Clip radial retaining rings are also available stacked (excluding the LC rings).
Technical Resources
E – External E Ring
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.
RE – External Reinforced E Ring
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.
C – External Crescent Ring
Ideal for low clearance applications where radial installation is preferred.
LC – External Interlocking Ring
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.
PO/POL – External Poodle/Poodle Light Ring
The PO ring features wide “ears” (resembling those of a poddle 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.
