Replacement bearings for small RC builds

This Hirobo HI2500110 ball bearing set comes as two 10x15x4 mm bearings supplied for use on rotor shafts, gear supports and similar mounting points in model helicopters and other small RC models. The aim is practical: swap worn bearings during routine maintenance to recover low friction and consistent running.

Installation notes: ensure correct orientation and a straight press fit, verify bearing seats and retainers for wear, and avoid hammering which can damage races. From a tuning perspective, fresh bearings reduce drivetrain backlash and support steady gear mesh and rotor balance during operation.

Packing: 2 pcs included, presented as one replacement pair for convenience.

How should I press these bearings in without damage?

Use a press or appropriate driver that contacts only the outer or inner race as required; apply even pressure and check alignment to prevent race deformation.

Will replacing these bearings help reduce vibration?

Yes, in many cases fresh bearings reduce drivetrain play and contribute to steadier gear mesh and rotor balance, which can lower vibration levels.
