How to add oil to motor bearings? Basic steps for adding oil to motor bearings

Ensure that the motor is powered off and cooled: Before adding lubricating oil, be sure to turn off the power and allow the motor to cool completely to prevent burns 

and short circuits.

Dismantling the motor cover: Typically, there is a nut or bolt on the top of the motor that can be unscrewed to open the motor cover. Please be careful not to damage 

other parts of the motor.

Find bearings: There are two main components inside the motor: rotor and stator. Bearings are located between the rotor and stator, typically cylindrical in shape and 

sometimes equipped with ball or roller bearings.

Remove old lubricating oil: If the motor has been used for a period of time, there may be some old lubricating oil on the bearings. Gently brush off these old oils with 

a brush or cloth.

Add new lubricating oil: Choose the type of lubricating oil suitable for motor bearings (such as full loss system oil, anti-wear hydraulic oil, etc.). Drop the oil onto the 

bearing and apply it evenly with a brush or clean cloth. Make sure not to add too much lubricating oil to prevent it from flowing into other components inside the 

motor, causing short circuits or other problems.

Reassemble the motor: Tighten the motor cover again, and then tighten the top nut or bolt.Check lubrication condition: Before the motor runs, check the lubrication 

condition of the bearings. If necessary, more lubricating oil can be added.Start the motor: After ensuring that the motor is running normally, reconnect the power 

supply and start running the motor.Oil filling methods for different types of motors

Iron oil seal: butter can be directly pressed into the bearing through the gap of the oil seal by hand.

Plastic oil seal: requires more meticulous operation, carefully remove the oil seal with the help of a sewing needle, and then add oil.

Motors with oil injection holes: Many newly produced motors are equipped with oil injection holes, which allow for direct refueling operations without stopping the 

machine.Old high-power motors: Some old motors with a base size of 280 or above also come with oil injection holes, which also support refueling without stopping 

the machine.
