Hirobo HI2500096 9 x 19 x 6.5 Thrust Bearing Pair  [HI2500096]

Helicopter thrust bearing details

This RC thrust bearing set is supplied as two matching units for general helicopter parts. The HI2500096 is intended to support axial loads where small-diameter thrust bearings are needed in rotor or driven assemblies.

Why it matters: these bearings control axial travel and preserve consistent axial positioning in rotating parts, which can affect swashplate behaviour and tail assembly alignment. They are intended for model helicopter repairs and replacements rather than any full-size machinery.

Fitment guidance:

• Confirm the housing and mating surfaces are clean and correctly sized before installation.
• Install the bearing squarely, and avoid applying side-loads which can cause indentation or damage.
• If lubrication is required, use a light, suitable bearing lubricant; too much grease may impede rotation.
• After installation, check axial clearance and ensure retaining hardware is torqued correctly to avoid binding under load.

Two pcs per package, suitable for routine maintenance and part replacement on model helicopters.
