Description
EL retaining rings are radially assembled external bowed locking circlips and are part of Rotor Clip’s radial retaining ring family. As a variation of a bowed E ring, the EL features a bowed design to eliminate end-play in an assembly and includes two prongs that extend from the inner circumference to the open end to lock the ring firmly into place.
