Reasons for Inflexible Operation of Supporting Roller
The factors affecting the flexibility of idler operation and its service life mainly include the following aspects.
(1) Manufacturing quality of idlers. The main manifestation is that the stiffness of the bearing seat is not enough to ensure the assembly accuracy of the idler, which restricts the flexibility of the idler operation.
(2) Seal lubrication and maintenance. Because the working environment of belt conveyor is relatively bad, generally speaking, the dust in the use site is very large, the seal form of bearing seat has a great impact on the flexibility of idler operation. If the seal is not good, the dirt will easily enter the bearing and cause the idler to rotate inflexibly. In addition, if the bearing grease is used with ordinary calcium-based grease, it will easily change color and dry, and it can not play a good lubrication. Effect
