Installation and cleaning of NSK deep groove ball bearings （1）

When the interference is large, oil bath heating or induction heating NSK deep groove ball bearing method can be used to install. The heating temperature range is 80℃-100℃, and the highest cannot exceed 120℃. At the same time, use nuts or other appropriate methods to fasten NSK deep groove ball bearings to prevent NSK deep groove ball bearings from shrinking in the width direction after cooling and causing a gap between the ring and the shaft shoulder. Single row tapered roller NSK deep groove ball bearings are installed Finally, the clearance should be adjusted. The clearance value should be specifically determined according to different operating conditions and the size of the matching interference. If necessary, it should be tested to determine. Double-row tapered roller NSK deep groove ball bearings and water pump shaft-connected NSK deep groove ball bearings have been adjusted in clearance at the factory, and there is no need to adjust them during installation.

After installation, NSK deep groove ball bearings should be subjected to a rotation test. First, use them on the rotating shaft or NSK deep groove ball bearing box. If there is no abnormality, use the power to run at low speed without load, and then gradually increase the rotation speed and load according to the operating conditions. And check the noise, vibration and temperature rise, if any abnormality is found, the operation should be stopped and checked. It can be delivered to use after normal operation test.
