Notes on bearing lubrication:

1. Most small motors have adopted double-sealed bearings (with "ZZ" after the bearing model), which are pre-oiled and do not need to be re-oiled.

2. Motors with oil filling and draining devices have been oiled at the factory, but after the motor is used, it needs to be regularly greased according to the time, grease brand, and oil filling amount on the oil filling label.

Bearing refueling method:

Open the oil filling nozzle, make sure the oil filling nozzle is clean, connect the oil filling nozzle with a manual oil gun or a pneumatic oil gun, and inject grease according to the time, grease brand, and refueling amount on the oil filling label.

If there is no way to control the amount of refueling, you can open the oil drain port when refueling. After refueling, let the motor run for 20-30 minutes to allow the excess grease to be discharged, then cover the oil filling nozzle and the oil drain port dust cover, and the refueling is completed.

If the bearing grease is added too much and the oil is not drained, it will cause the bearing to fail quickly.

Types of lubricating grease:

When refueling, be sure to read the grease brand on the oil filling label and use the correct lubricating grease. If the added grease is incompatible with the original grease, it will greatly reduce the life of the bearing.
