3RACING Double Rubber Sealed Bearings 4x10x4mm (10 pcs) - 3RB-MR104-2RS_10 Racing Pack  [3RB-MR104-2RS_10]

Race-Oriented Sealed Bearings from 3RACING 3RB-MR104-2RS_10

The 3RACING Double Rubber Sealed Bearings 4x10x4mm (10 pcs) - 3RB-MR104-2RS_10 are supplied with dual rubber seals to limit ingress of abrasive particles that increase rolling friction and wear. The compact 4x10x4mm geometry suits common hub and shaft applications in competitive small-scale setups where controlled maintenance intervals are desirable.

Competitive Fitment Notes

These sealed bearings are appropriate for applications that balance low rolling resistance and contamination protection. Use them in wheel hubs, idler shafts, and gearbox positions where a sealed unit aids consistent lap times by reducing unexpected drag from ingress.

Setup and Servicing Tips

When installing, ensure the bearing seat is clean and concentric to avoid preload from misalignment. Avoid forcing solvents into the seal lip; instead, replace bearings when internal contamination is suspected to maintain predictable handling.
