bearing selection recommendation - mining industry
Bearing application equipment:
mining vibrating machinery, vibrating screen machinery, vibrating motor.
Characteristics of bearing application conditions:
harsh working environment, high environmental humidity, many dust particles, long continuous working time of equipment, high operating temperature, and strong vibration and impact during work.
spherical roller bearings【A.MA series】
cylindrical roller bearings【NNU series】
1. The general dimensional tolerance is P6, and the rotation tolerance is P5;
2. Since the working conditions are mostly heavy load and impact load, the bearing generates a large amount of heat, so the initial bearing clearance generally chooses C3, C4 or a special customized large clearance;
3. It is recommended that the cage be machined brass and guided by the outer ring to be suitable for eccentric loads.
