At present, the equipment that uses precision bearings is becoming more and more refined, and the grease used in NSK bearings must have the following functions:
(1) With the same operating life as the bearing, the maintenance cycle should be delayed as much as possible, the downtime should be shortened, and the labor productivity can be improved.
(2) At a high speed of dn>5×105, it is necessary to ensure that the temperature rise of the motor is low and oil is not dumped, thereby reducing power consumption and protecting the motor.
(3) Its scalar content control is under the inevitable standard, and the pollution of the equipment noise to the situation is minimized.
(4) Under the premise of ultra-low temperature work, it guarantees the flexibility of starting and running of bearings, common problems of NSK bearings. Guaranteed minimum output power.
The cleaning of the removed NSK bearings is divided into rough cleaning and fine cleaning, and they are placed in the container, and the metal mesh pad is placed first so that the bearing does not directly contact the dirt of the container. During rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing, and it should be noted. In the coarse cleaning oil, use a brush to remove smooth grease and adhesions. After roughly cleaning, transfer to fine washing.
