Electric motor bearings or motor bearings, are a special type of bearing used in electric motors or motors. The most common type is rolling bearings. The motor bearing used in the motor is a part that supports the shaft. It can guide the rotation of the shaft and also bear the idling parts on the shaft. In the motor, the bearing is also used to connect the motor parts together, allowing the transfer of any force and movement, and is an important accessory for the rotating part of the motor.
There are four types of bearings commonly used in motors: roller bearings, sliding bearings, spherical bearings and oil-containing bearings.
Electric motors are widely used in various mechanical equipment. The quality of electric motors is related to the running stability of the bearings used to a certain extent. It requires the bearings to be low-noise, economical and with a simple supporting structure. Deep groove ball bearings are usually used.
Working Principle:
Motor bearings use smooth metal balls or rollers and lubricated inner and outer ring metal surfaces to reduce friction. These balls carry the load and support the motor shaft, allowing the motor (rotor) to rotate smoothly.
working principle is to use smooth metal balls or rollers and lubricate the inner and outer ring metal surface to reduce friction, and through these balls to support the load and spindle so that the whole motor (rotor) can rotate smoothly.
Types of bearings used:
Most small and medium-sized motors use rolling bearings.
Large and medium-sized motors also use rolling bearings.
Ball bearings (deep groove ball bearings) are used at both ends of small motors.
