Technical note on 3RACING 5x11x4mm shielded bearings

The 3RACING Double Metal Shield Bearing 5x11x4mm is supplied in batches of ten and offers a compact, shielded rolling element for common RC drivetrain positions. These bearings are useful when setting up a car for consistent low drag across multiple assemblies.

Construction and contamination control

Dual metal shields provide a robust barrier against fine particulates while maintaining low running friction. The shields reduce ingress without adding significant axial width, preserving fitment in tight housings.

Workshop and tuning considerations

Fit these bearings in wheel hubs, gearbox idlers and pinion supports where the 5x11x4mm specification is required. For competitive tuning, install with straight seating using a dedicated driver and perform light lubrication appropriate to your racing conditions.

Common positions include small wheel hubs, idler shafts and certain gearbox bearings that specify 5x11x4mm. Check the kit parts manual for exact locations.
Use a proper bearing press or a correctly sized driver and apply even pressure to the outer race. Avoid hammering the inner race to prevent roller set and premature failure.
They are appropriate for typical high rpm hobby brushless use. For extreme rpm or endurance racing evaluate bearing grade and consider precision or ceramic options based on thermal and load requirements.
