Small-scale bearing details

This Hirobo HI2500110 ball bearing set is supplied as two 10x15x4 mm bearings for use in rotor shafts, gear mounts and other similar locations on model helicopters and compact RC models. The pack is intended for routine replacement tasks that restore smooth rotation and reduce friction where moving parts run under light loads.

Installation notes: verify the bearing size and seat condition before installation, press bearings evenly to avoid misalignment, and check retaining clips or fasteners. In terms of setup, bearings are a subtle yet important component that help maintain tight gear engagement and stable rotor operation, so replacing worn items is a standard diagnostic step.

Packing: 2 pcs included as a matched replacement pair for straightforward exchange.
