Low noise electric motor ball bearings to fit shafts from 10mm to 30mm diameter.
SMB Bearings’ electric motor ball bearings are rated EMQ2 for very low noise or low vibration applications. These bearings are individually tested to ensure low levels of noise and vibration. Various radial play groups can be supplied but the most commonly stocked are CN (standard) radial play and C3 (loose) radial play. We also stock noise tested smaller EZO bearings which are suitable for electric motors.
Usually supplied in SAE52100 chrome steel, our electric motor bearings can withstand heavy radial loads and moderate thrust loads in both directions. Many other sizes can be supplied as low noise but these are the most commonly used.
