【THB】bearing selection recommendation - mining industry
Industry: Mining
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.
Selection recommendation:
spherical roller bearings【A.MA series】
cylindrical roller bearings【NNU series】
Bearing features:
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.
