Hirobo HI2500110 10x15x4 mm Ball Bearing Set for RC Shafts, 2 pcs  [HI2500110]

Compact ball bearings for RC maintenance

This Hirobo HI2500110 ball bearing set is a small-scale RC accessory supplied as two pcs of 10x15x4 mm bearings intended for rotor shafts, gear supports and similar locations in model helicopters and small RC models. The description focuses on practical use: replacement during maintenance, restoring smooth rotation, and supporting moving parts that require low friction and stable running.

Installation notes: check fitment before final assembly, press bearings squarely into housings or shafts to avoid misalignment, and inspect bearing seats and retaining hardware for wear. For tuning and setup, bearings play a background role by reducing drivetrain play and helping maintain consistent gear mesh and rotor balance; replacing worn bearings is a common step when diagnosing vibration or increased drivetrain resistance.

Packing: 2 pcs included, packaged as a single bearing pair for replacement use.
