Ceramic High Speed Wheel Bearing (5/8″ ID)

Precision Ceramic Wheel Bearings:
Faster ET’s and Lap Times – Ceramic bearings have 1/10th the friction of steel which means faster ET’s and lap times! Can you push your car with one hand?
60% Lighter Weight – Silicon Nitrate balls weigh 60% less than steel balls of the same size. Reduce your bearing rotating weight!
Longer Life – Ceramic Bearings last up to 5 times longer than steel!
Cooler Running – Ceramic Bearings have no micro weld adhesion between the balls & races which means lower friction. Ceramic also has a lower amount of thermal expansion which also reduces temperatures. Bearings run cooler and vibration levels are lower at high RPM
No Special Handling or Cleaning – If they get sluggish rinse with paint thinner, put a drop of oil in and go racing!
