3RACING Double Metal Shield Bearings 12x18x4mm (10 pcs) - 3RB-6701-ZZ/10 Racing Grade Bearings  [3RB-6701-ZZ/10]

Racing Focused Shielded Bearings

The 3RACING Double Metal Shield Bearings 12x18x4mm (10 pcs) - 3RB-6701-ZZ/10 are designed to deliver consistent rotational performance in common racing-fit locations. At 12 x 18 x 4 mm, these bearings allow precise component alignment and reduced drag for tighter lap times in tuned setups.

Shielding and Durability for Competitive Use

Double metal shields provide effective contamination mitigation while maintaining minimal friction. This construction helps protect internal elements under varied track conditions without adding unnecessary running resistance.

Integration and Tuning Notes

These bearings suit wheel hubs, small gearbox assemblies and accessory pulleys used in competitive builds. For setup tuning, verify radial clearance and bearing seat concentricity to avoid preloading and to preserve bearing life.
