Product Benefits:

  • Rubber shielded bearings add sealed protection against dirt, dust, and debris for off-road and mixed-surface RC use.

  • Best choice when protection matters more than the lowest possible rolling drag.

  • Maintenance tip: after wet, dirty, or dusty runs, clean around the bearing area, dry the vehicle, and re-lube as needed.

Reason to Purchase:

Choose rubber shielded bearings for off-road, dusty, dirty, clay, grass, parking-lot, or debris-prone running because they provide more contamination protection than metal shielded low-drag bearings.
