The vibrating screen bearing has two rows of rollers, one column mainly bears the load on one side, but also can bear the axial load of any column. It has a high radial load capacity, which is more suitable for heavy loads or vibration loads, but it also has limitations, such as being unable to withstand pure axial loads.

The main cause of mechanical failure in screen decks is vibration. Even the frame, body, and bearings are affected by this. The larger the screen the bigger the effect. The vibration will crystallize the …

For mechanical equipment, bearings have a high incidence area of faults. A problem for bearings is that their fault characteristics include a vibrating screen exciter which is weak and thus easily covered in strong background noise, hence making the noise difficult to remove. In this paper, a noise reduction method based on singular value …

2. Start vibrator(s) only for a few seconds, then stop. 3. Observe direction of screen vibrator rotation. If screen vibrator is not rotating in correct direction, lock out/tag out energy source and reverse rotation. To reverse rotation of three-phase vibrator, reverse any two of the three power supply wires.

Vibrating screen bearings (for example 22340 CCJA/W33VA405) are widely used in mine vibrating machinery, vibrating motors, etc. The working conditions of these bearings are very bad. The humidity, revolving speed temperature is high. Moreover, there is strong vibration and shock, which resulting in very large workload.
