3RACING 3RB-MR105ZZ/B3/10 Double Metal Shield Bearings 5x10x3mm (10 pcs)  [3RB-MR105ZZ/B3/10]

Improve drivetrain efficiency with 3RACING bearings

The 3RACING Double Metal Shield Bearing, sized at 5 x 10 x 3 mm, ships as a 10 piece pack. These compact bearings reduce friction to help your RC run smoother and extend the service life of gears, axles and motor shafts. The metal shields offer extra defence against dust while keeping rolling resistance low.

Suitable uses and compatibility notes

These bearings work across a broad range of RC models, from street-style racers to heavier basher builds where lowering mechanical drag matters. In high-rev or high-load applications the shielded construction helps maintain consistent performance and reduce wear on mating parts.

Fitment and maintenance guidance

For best results lightly oil or use a thin synthetic grease before fitting to avoid added drag. Check bearings periodically, clean out grit and relubricate to preserve smooth running. The 5x10x3mm form factor makes swaps quick for both newcomers and seasoned hobbyists.
