Hirobo HI2507003 M3.0 E-ring Retaining Clips Pack 10 pcs for RC Helicopter Parts  [HI2507003]

Hirobo M3.0 E-ring product summary

The Hirobo HI2507003 E-ring M3.0 comes as a ten-piece set of small axial retaining clips intended for routine replacement and service on scale RC models. These E-rings slot into a machined groove on an M3.0 shaft to prevent lateral movement of gears, linkages, and rotating components commonly found on RC helicopters and similar machines.

Choose this pack when a loose shaft end, a worn clip, or a scheduled rebuild calls for a simple retention solution. The low-profile design secures assemblies without adding appreciable shaft length, making it suitable where space is tight.

To fit, press the E-ring into the shaft groove until it fully seats and engages. Inspect both the groove and mating parts for burrs, wear, or deformation before assembly, and replace any ring that shows bending or loss of spring tension to preserve reliable axial positioning. Keep spare rings on hand to avoid field downtime.
