ASC21105 Bearing 4x8x3mm

These precision radial ball bearings reduce rotational friction and enhance drivetrain efficiency for popular miniature radio-controlled vehicle platforms. Engineered with exact dimensions, the components fit smoothly into transmission housings, steering blocks, and wheel hubs without binding. They integrate seamlessly into standard micro chassis layouts to provide a silky smooth rotation point under high RPM operations. The durable steel construction and protective metal shields resist dirt intrusion and premature wear during intensive track sessions. Hobbyists can utilize these reliable replacements to eliminate drivetrain drag and improve overall mechanical performance. Elevate your micro build with professional-grade bearings designed for long-lasting operational smoothness.

• Features precision dimensions measuring four by eight by three millimeters for accurate fitment across various miniature vehicle locations.

• Constructed from high-grade bearing steel selected to endure high rotational speeds and heavy radial loads without premature failure.

• Designed with low-friction shields that prevent dust, dirt, and track debris from entering the internal rolling elements.

• Engineered for direct compatibility with Team Associated RC18 series platforms including the RC18T, RC18R, and related micro variants.

• Packaged individually or in standard factory configurations to service specific upgrade or routine maintenance requirements.

• Ultra-smooth internal ball race design significantly reduces mechanical drag to maximize battery run times and top-end speed.

• Essential maintenance hardware that ensures reliable, wobble-free rotation across transmission shafts, steering assemblies, and wheel axles.
