In general, the normal temperature of bearings should be maintained at 35-60 ℃. If the bearing temperature is too high during use, the following reasons may exist:

1. The radial clearance of the bearing is too small

Due to the large load and high frequency carried by the bearings on the vibrating screen, and the constantly changing load, the bearings must use large clearance. If a bearing with regular clearance is used, the outer ring of the bearing must be ground again to create a large clearance.

2. The bearing gland is pressed too tightly

There must be a certain gap between the gland and the outer ring of the bearing to ensure normal heat dissipation and certain axial movement of the bearing. This gap can be adjusted through the sealing gasket between the end cover and the bearing seat.

3. Poor bearing lubrication

Lack of oil or contamination of the bearing oil can cause overheating of the bearing. At this time, it is necessary to inject oil, clean, replace oil, and seal the bearing, check the oil quality and injection situation, and there may also be bearing wear or bearing quality issues.
