Avid Rear Ceramic Bearing

The Avid 14x25.4x6 Ceramic Engine Bearing offers the maximum performance and reliability to your racing engine at an unbeatable price. The bearing specs are Abec5, 9 G3 Si3N4 Ceramic Balls, PA66 with 30 Glass Fiber Cage, and Chrome Steel 52100 Rings. It has no seals to allow for proper lubrication from the oil in your fuel. A ceramic engine bearing can allow most RC engines to spin an extra 500 rpm with less drag and the life of the bearing is far greater over a steel bearing. Another benefit to ceramics is the weight difference in the balls allowing for less rotating mass.

 

Tips

  • Diagnosing: If you hold the head of the engine with your hand and a rattle sound dissapears then you have a worn out rear bearing. The risks/issues of a bad rear bearing are not holding a tune, crank can get worn, and worst of all the bearing comes apart and eats your piston/sleeve.
  • Installation: The best way to install is to use a bearing puller/installer, OFNA makes a very affordable one. If you place the new bearing in the freezer for 15 minutes it will be easier to install.
  • Positioning: For proper lubrication, face the open side where you can see the balls to the rear of the motor (not the clutch side).
  • Break In: For the first run of these bearings, Avid suggests that you fatten your motor up on the high-end needle so the ceramic balls will seat instead of skidding them.
