What should I do if the bearing temperature is too high?

After the bearing is installed, check it to ensure that the bearing is installed in place, rotates flexibly, and has no seizure. If the bearing is installed improperly, the temperature of the bearing will rise rapidly and be damaged, or even major accidents such as bearing seizure and fracture
The recommended tolerance for the working conditions of the inner ring is n6 p6 r6, and the recommended tolerance for the working conditions of the outer ring is K7 M7
Solution of bearing temperature is too high:
1. Too much lubricating grease will increase the resistance of the lubricant; choose the correct grease and use an appropriate amount
2. Too small clearance causes excessive internal load;
3. Installation error; improve bearing seat accuracy and installation method;
4. Friction of sealing equipment;
5. Creeping of bearing ring; improve the fit between bearing and bearing chamber
6. The intrusion of foreign matter has caused the deformation of the bearing (bearing sleeve, cage).
7. It is recommended to use ceramic ball bearings. HQ series bearings are not less rigid than steel balls, and they are not easy to generate heat! The temperature of the ceramic ball bearing does not exceed forty degrees
