Documentation
Description
LC retaining rings are radially assembled external interlocking circlips and are part of Rotor Clip’s radial retaining ring family. The LC ring is produced in two identical halves that interlock into a groove on a shaft. Once assembled, the rings are dynamically balanced, making them particularly effective at retaining assemblies with extremely high rotational speeds.
