In the original design NTN bearing installation site should take into account the disassembly problem -
If the bearing use interference fit to install, the shaft or the bearing hole should be set in the disassembly with groove in order to remove the ring.
If removed angular contact ball bearings and to use it: 1.
Should avoid direct hit the bearing ring, 2.
Remove the force should not pass through body, 3.
Once a bearing is removed, it must be carefully cleaned and can't use 'fierce' flame.
Remove the NTN bearing under repair, the first recorded appearance of angular contact ball bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing.
Common use gasoline, kerosene as a cleaning agent.
Tear open come down to the bearing cleaning, coarse and fine fine cleaning cleaning, respectively in the container, put a metal mesh bottom first, make the angular contact ball bearing is not direct contact with dirt from the container.
Coarse when cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to.
In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning).
Fine cleaning, NTN bearing side rotation in the cleaning of oil, while carefully cleaned.
In addition, the clean oil is always kept clean.
Assembly site should be kept clean, no dust.
To avoid bearing from dust, moisture and contaminants -
Pollutants diagonal contact ball bearing is bad operation and service life.
Check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness.
For bearing ring mating surface coated with a little oil or a little fat.
To ensure that the shaft and bearing hole has a 10 degrees -
Guide the chamfering of 15 degrees.
Don't be cool bearing: condensation of water can lead to bearing and the bearing of mating surface rust.
After installation, loading the NTN bearing lubricant, check whether the angular contact ball bearing configuration is working properly.
