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

Precision shield bearings for racing setups

The 3RACING Double Metal Shield Bearing, 5 x 10 x 3 mm and supplied in a 10 piece pack, is engineered for tuned drivetrain performance. The double metal shields maintain consistent clearance while protecting internal components, helping to deliver predictable bearing behaviour under sustained high rpm.

Competitive application and tuning

Ideal for race and sprint configurations where low friction and repeatable response are critical, these bearings suit motor shafts, wheel hubs and gearbox outputs that accept 5x10x3mm parts. Their shielded architecture supports stable temperature and contamination control during extended runs.

Installation best practice for performance

Press the bearing using a dedicated tool that bears on the outer race to avoid inner-ring damage. Use light, purpose-grade oils for high rpm use and check bearings as part of your setup routine to detect early wear. These straightforward bearings offer a balance of durability and low drag for serious hobbyists and racers.
