    SKU: #ENK-012C-MX

    Ceramic MX RC Engine bearing kits are specially designed for problematic racing engines. These bearings have ceramic balls, a high speed, heavy duty, retainer and a special internal design that can withstand higher radial and thrust loads than standard bearings. Ceramic hybrids are lighter, capable of achieving higher RPM’s and sustaining higher operating temperatures than traditional bearings. Whenever using a ceramic hybrid bearing in an RC Engine, we suggest leaving both seals on for the front bearing and one seal facing the inside of the motor on the rear bearing. This protects the RC engine from possible bearing failure.
