Traxxas 5101 Ball Bearings 12x21x5mm Blue

Blue rubber sealed ball bearings, 12x21x5mm. Two per package.

Rubber seals keep grit and water out of the race, which is what determines how long a bearing lasts in an off-road truck. Once a seal is breached the grease washes out and the bearing pits quickly, costing runtime and efficiency well before it starts making noise.

Fits: Traxxas Maxx Slash (102076-4) and other Traxxas models using 12x21x5mm bearings.

Direct replacement for the factory bearings.
