7805 bearing is high quality angular contact ball bearing

Accuracy grades of angular contact ball bearings 7805 bearing include dimensional tolerances and rotational accuracy.
7805 bearing application: machine tool spindle, high frequency motor, combustion steam turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, low noise type cooling tower, coating equipment, machine tool slot plate, arc welding machine.
Maintenance method for 7805 bearing:
1, when the 7805 bearing runs to a certain period (or maintenance period), the bearing will be removed;
2. Soak the 7805 bearing with the diesel oil or kerosene for cleaning. If there is a technical condition, it is best to open the seal cover for cleaning.

3. Dry the cleaning oil after cleaning, and check the appearance of damage;
4. Use a wooden rod (preferably hollow tube) with a diameter of about 150mm and equal inner diameter of angular contact ball bearing, and one end is fixed with a bearing;
5. While rapidly rotating the bearing by hand, the other end of the stick (woodpipe) is placed on the ear or the microphone of the audio amplifier to listen to the noise of the bearing rotation;

6. Transversely move the rod after fixing the bearing to check whether the bearing is worn and loosened;
7. Take a bucket and melt proper amount of grease (high quality yellow dry oil) with gentle fire (not too hot), and soak the tested bearing in the bucket until there is no bubble overflow.Take out the bearing before grease cooling, the amount of residual grease is small.Take out the angular contact ball bearing after the grease is cooled, and there is a large amount of residual grease.Determine the amount of residual grease according to the need.
8. Wipe the grease outside the bearing with a soft cloth or toilet paper and assemble the 7805 bearing on the pulley in its original state, and the maintenance work is over.
