Read more Love Life, Love Your Hobbies - There are more than 50,000+ models of bearings in the world, We can offer 10,000+ of them, And 4,050+ models remain in stock. That's what we love. Focus on bearings, love life. 683zz Ball Bearing 3x7x3mm ABEC-7 Quality Bearings [ 10 Pcs ] Electric Motor Bearings The purpose of a bearing in an electric motor is to support and locate the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The bearings should be able to operate at low and high speeds whilst minimizing frictional losses. At the same time, the bearing must be economic and require absolutely minimal maintenance (if any). Noiselessly - Nylon cage, G5 Class Steel Balls, With Grease. Roll Smoothly & Without Backlash - 52100 Chrome Steel. Suitable for Brushless Motors, Propellers, Fans, RC Engines.
