Tamiya 42109 - 840 Flanged Bearings 2-Pack High Durability  [42109]

Upgrade with Tamiya 42109 - 840 flanged bearings

Modelers seeking consistent spin and low maintenance will find these flanged sealed bearings useful. They are built to sit securely while providing smooth rotational movement across common RC assemblies.

Engineering and measurements

The bearings feature an 8mm outside diameter, a 4mm bore, and a 3mm thickness, a compact profile well suited to shafts and gearboxes that require low friction and precise alignment.

Compatibility notes and fitment

The flanged edge stabilises the bearing in housings and reduces the chance of axial shift during aggressive running. They are handy for replacements and modest performance upgrades in many small to mid scale models.
