In order to better extend the service life of the motor bearings and ensure the normal operation of the bearings, the motor bearings need to be lubricated and maintained regularly. The main effect of grease on motor bearings is lubrication, protection and sealing. Many details should be paid attention to in the motor lubrication and maintenance, such as: how much do you need to add for the first time? If the amount of grease is too large, the friction torque will increase, the temperature will rise, and the grease consumption will increase; while if the amount of grease is too small, reliable lubrication will not be obtained and dry friction will occur. In order to solve the confusion of the majority of users, today Harbin Bearing Group analyzes how much grease needs to be added to the motor bearings for the first time?

 1. Sealed (lifetime lubrication)/high-speed bearing

 30% of bearing internal space (sealed bearing)

 2. Non-sealed bearings

 ①Fill up the inner space of the bearing

 ②Add 30-50% grease in the bearing seat

 ③Ensure good sealing and lubrication

 ④If the speed is low, the amount of grease can be greater than 50%

 Appropriate grease is the basis to ensure good lubrication and maintenance of motor bearings. In addition, Harbin Bearing Group reminds everyone that it is forbidden to mix greases of different brands because the thickeners, base oils and additives used in greases are different. Later, it will cause changes in the colloidal structure, which will increase the oil separation, change the consistency, and affect the mechanical stability. Pay attention to regular filling and replacement of grease. When adding new grease, squeeze out the waste lubricating grease until you see the new grease at the grease outlet. The fatliquoring process must be kept clean to prevent the mixing of mechanical impurities, dust and sand.
