Product Benefits:

Rubber shielded bearings add sealed protection against dirt, dust, and debris for off-road and mixed-surface RC use.
Choose rubber shielded bearings when protection matters more than the lowest possible rolling drag.

Reason to Purchase:

Rubber shielded bearings are the better choice for dusty, dirty, clay, sand, or debris-prone RC conditions because they add sealed protection compared with metal shielded bearings tuned for lower drag.
