What should we do if the idler of TD75 universal fixed belt conveyor does not operate flexibly?

1. Ensure the manufacturing accuracy of the idler. For example, the accuracy of the inner hole of the stamping bearing seat should reach Grade 3. The dimensional tolerance, coaxiality and ovality of both ends of the pipe body must meet international requirements and must not exceed the tolerance. Strict quality inspection shall be carried out for the products to ensure that all the ex factory products are qualified.

2. In terms of seal lubrication, proper lubricating materials, such as lithium grease, can improve the lubrication of the bearing, which is very necessary to extend the service life of the idler.

3. The centripetal ball bearing plastic seal palace seal structure is adopted, which can ensure that the idler is under reasonable stress when working, and at the same time, the dust prevention effect is good, the resistance is small, the assembly and disassembly are convenient, and the maintenance is convenient, which can effectively reduce the operating cost of the conveyor.
