We use the belt machine not only to check the operation of the roller, but also pay attention to the operation of roller bearings.Belt conveyor roller is very important, roller bearings are also very important, in fact, they are a roller accessories, roller can run properly with the bearing has a direct impact, then how do we judge the roller bearing good or bad?
To determine whether the roller bearing can be reused, we must first use the correct removal tool to avoid damage to the roller bearing.After the demolition we have to see whether the bearing parts broken or ball damage, to focus on checking its dimensional accuracy, rotation is smooth, whether there is abnormal.If the bearing has been damaged, please replace. We have to regularly check the operation of the roller, regular maintenance, if the roller does not turn, it will seriously wear the belt, the loss will be great.
The quality of the roller bearing also directly affects the precision of the roller bearing installation. The precision of the bearing bearing affects the axial positioning density of the bearing and also affects the fit of the roller bearing and bearing.So the quality of the roller accessories is very important, it directly affects the quality and life of the roller.
It is important to improve productivity and economy through proper periodic inspection, early detection of faults, prevention of accidents,At the same time do regular cleaning on the roller bearing parts, to extend the life of the bearing have a certain role.
In order to determine whether the removal of the bearing can be reused, to focus on checking its dimensional accuracy, rotation accuracy, internal clearance and with the surface, raceway, cage and seals and so on.

1.Bearing inspection work during the operation
Rolling bearings lack of oil, you will hear the “gulu” sound; if you hear no “geng” sound, may be the bearing steel ring break.If the bearing mixed with sand and other debris or bearing parts with mild wear, there will be a slight noise.

2.Check the roller bearing parts after the inspection work?
First look at the roller bearing rolling body, the table is not broken steel ring, corrosion, scars and so on.And then hand pinch bearing inner ring, and make the bearing pendulum, the other hand forced to push the outside circle.If the bearing tight, the outer ring should be rolling smoothly, rolling without vibration and significant stuck appearance, stopped after the outer ring did not reverse appearance.Otherwise that the bearing can no longer be used.Left hand stuck outer ring, right hand pinch inside the steel ring, forced to push in all directions, if the move is very loose, that is serious wear and tear.

On the results of the inspection, can be judged by people who proficient in the bearing.The criteria for judging vary according to mechanical properties and importance, as well as the inspection cycle.If the following damage, the bearing shall not be reused, must be replaced.
?
1)Roller accessories bearing parts of the fracture and defects.
2)Scrolling of the rolling surface.

If the roller is an indispensable part of the whole conveyor system, then the roller bearing is the roller depends on the location, carrying the role of the roller and run the above also to illustrate the importance of roller bearings, axial bearing capacity Will directly affect the life of the roller, affecting the efficiency of the entire conveyor system.
