After the bearing is installed, it should be inspected to ensure that the bearing is installed in place, rotates flexibly, and has no sticking phenomenon. If the bearing is installed improperly, the temperature of the bearing will rise rapidly and cause damage, and even major accidents such as bearing sticking and breakage may occur.
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 to excessive bearing temperature:
1. Too much grease will increase the resistance of the lubricant; choose the correct grease and the 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 rings; improving the coordination between bearings and bearing chambers
6. The intrusion of foreign matter causes the deformation of the bearing (bearing sleeve, cage).
7. It is recommended to use ceramic ball bearings. HQ series bearings are no harder than steel balls and are not prone to heat! The temperature of ceramic ball bearings does not exceed 40 degrees
