Tamiya F104 Low-Friction Ball Bearing Set BS-F104/V1 by 3Racing  [BS-F104/V1]

F104 bearing kit overview

This ball bearing set is intended for the Tamiya F104 chassis and supplied as BS-F104/V1. It is offered as a direct replacement for worn or lower-grade drivetrain bearings used in 1/10 formula and touring conversions that use the F104 platform.

Functionally, the bearings reduce rolling resistance in rotating assemblies such as wheel hubs, motor output shafts and gearbox interfaces, which helps improve throttle response and keep drivetrain losses predictable during runs. This listing refers to fitment for F104-style RC assemblies only and does not imply use in full-size or non-RC equipment.

Fitting is typically a straightforward bearing swap: remove the old bearings, clean the seating areas, and press the new bearings in square to avoid misalignment. After fitting, verify free spin and check for side play at the hub or motor shaft, and maintain performance by keeping bearings clean and lightly lubricated with a suitable RC lubricant.
