Hirobo HI0402327 bearing for S-30 clutch with collar  [HI0402327]

Replacement bearing for S-30 clutch

This Hirobo HI0402327 bearing is an RC-scale replacement part intended for use with S-30 clutch assemblies on model helicopters. The part includes an integrated collar feature to aid axial positioning during installation and to keep the bearing aligned within the clutch stack.

Use this bearing when restoring worn clutch components or when a precise collar fit is required to maintain clutch alignment. The component supports the clutch's role by providing a consistent running surface for the clutch drum or hub, helping maintain predictable engagement characteristics when combined with properly adjusted clutch shoes and springs.

Installation notes: confirm the bearing seats flush against the collar and clutch housing, inspect for axial play after fitting, and replace if any roughness or excessive wear is detected. This is a direct accessory for RC helicopter clutch assemblies and is described strictly as a model-scale part.
