Product Benefits:

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

Reason to Purchase:

Rubber shielded bearings are the better choice when your Kyosho runs on dirt, dusty pavement, gravel, grass, or debris-prone surfaces because the seals help protect the bearing races compared with lower-drag metal shielded bearings.

Fitment Note:

Choose rubber shielded bearings when added contamination protection matters more than the lowest possible rolling drag.
