Tamiya 42109 - 840 Precision Flanged Bearings Pair  [42109]

Tamiya 42109 - 840 bearings for consistent rotation

RC enthusiasts who value steady bearing behavior will find these flanged sealed units useful. They are made to reduce wobble and keep shafts turning smoothly under typical model loads.

Design details and sizing

The flange profile aids location while the bearing dimensions - 8mm outer diameter, 4mm inner diameter, 3mm width - suit many small-scale motor and axle applications. The size helps limit friction and maintain predictable movement.

Installation advice and retention

Thanks to the flange, these bearings are less likely to shift once pressed into place, ideal for use in transmissions, wheel carriers, and steering linkages. They work well for both routine replacement and targeted upgrades.
