NAF rolling mill bearings are the bearings used on the roll necks and rollers of metallurgy, mining, and other rolling mill stand. Generally, NAF cylindrical roller bearings are used to bear radial loads, NAF deep groove ball bearings or NAF angular touch ball bearings, or tapered roller bearings with radial design or thrust design to bear axial loads. For rolling mill bearings, regular maintenance is required, and good operation and use habits must be developed at the same time. Only in this way can the service life of the rolling mill be extended, the operating rate can be improved, and a better guarantee can be provided for the stable production of the enterprise. So how to check the work of the rolling mill bearings that have been completed by the new device?
After the rolling mill bearing installation is completed, to check whether the installation is correct, it is necessary to conduct a workplace inspection. It can be rotated by hand to confirm whether the rotation is smooth. Check the project for poor work due to foreign matter, scars, and indentations, uneven rotational torque due to poor installation and poor processing of the installation seat, excessive torque caused by too small clearance, installation errors, and seal conflicts Wait. It can work initially if nothing else. Check whether there is vibration, movement, whether there is contact with the rotating parts, etc., and enter the power work after confirming that there is nothing special. The working condition starts from no load and low speed, and gradually increases to work under rated conditions. The items to be checked during the trial work are: whether there is any special movement, bearing temperature transfer, lubricant leakage, discoloration, etc. If any abnormality occurs during the trial work, the work should be stopped immediately, the mechanical equipment should be checked, and the bearing should be removed for inspection if necessary.
The service life of rolling mill bearings is not only related to the quality of the bearings but also closely related to the conditions of their installation and use. For this reason, we should pay attention to the technical requirements of the bearing device and abide by the relevant operating procedures.
