Difference between double ball bearing motor and ordinary motor

Double-bearing motor has high-end, long life and low noise. According to the public information, the double-bearing motor is a relatively high-end motor, and two bearings are selected before and after the motor. The advantages of double bearing motor are long life, aging resistance and low noise. The common motor only has a bearing at the front end, supplemented by some lubricating oil to reduce friction, which has low calorific value and low cost. Compared with the double-bearing motor, it has short service life and high noise.
