Smooth running bearings for RC drivetrains

For keeping wheels and gears turning with minimal friction, the 3RACING Double Metal Shield Bearing 1.5 x 4 x 2 mm delivers dependable rotation. Built for hobbyists who want robust, low-maintenance bearings, these parts suit regular running and incremental upgrades.

Shielded setup for longer service life

The double metal shields block dust and grit while still allowing steady spin. That extra protection helps reduce wear and keeps bearing play to a minimum when you run on dusty surfaces or in damp conditions.

Compatible with common axles and hubs

These bearings match many standard RC shafts and wheel hubs, making them a straightforward replacement for worn stock bearings. They work well in touring cars, 1/18 scale buggies, and other compact models.
