Hirobo HI0402327 Collar Bearing for S-30 Clutch  [HI0402327]

Overview: S-30 clutch collar bearing

The Hirobo HI0402327 bearing is an aftermarket replacement component designed for S-30 clutch assemblies used in RC helicopters. The integrated collar aids axial positioning and helps preserve the bearing's alignment within the clutch stack.

Install this bearing when worn clutch elements are being renewed or when a precise collar fit is required to keep the clutch geometry correct. The bearing gives a reliable running surface for the clutch drum or hub and supports repeatable engagement when used with properly set clutch shoes and springs.

Service advice: confirm the bearing is fully seated against the collar and clutch housing, check for axial play and smooth rotation after fitting, and replace the part if any roughness or damage is found. This is supplied as an accessory for model-scale RC helicopter clutch assemblies.
