Precautions for installation of bearing by needle rolling manufacturer

If there are burr, iron pin, dust and other dirt in the material processing of locating pin, it is necessary to ensure the cleaning of equipment surface and installation natural environment. It will cause noise and vibration when the ceramic locating pin is running, and even damage the dovetail guide rail and the turnover body.

Since the locating pin clamp is in front of the original factory, it is necessary to clean the rolling bearing before the equipment. In order to maintain the surface of the dovetail guide rail and the turnover body is not rusted, and the anti rust agent or anti rust treatment grease is introduced between the dovetail guide rail and the turnover body. Therefore, it is necessary to clean up with clean motor gasoline and gasoline, and then apply clean, high-quality or high-speed high-temperature lubricating fluid before application. However, some totally enclosed rolling bearings and the rolling bearings coated with moistening and antirust double use vegetable oil do great harm to the service life and vibration noise of the rolling bearings due to the cleanliness that does not need to be cleaned.

Different types and the same type of different models of lubricating grease characteristics are quite different, to choose the right lubricating grease. Lubricating grease is made of base oil, emulsifier and preservative. The allowable rotation limit is different, and the properties of lubricating grease are determined by the base oil emulsifier, which is also related to the wettability. The wear resistance of emulsifier determines the wear resistance of lubricating grease. General high viscosity base oil is suitable for ultra-low temperature and high speed; low viscosity base oil is suitable for high temperature and long time load. Different brands of lubricating grease can not be mixed, and even the same emulsifier of lubricating grease will cause damage to each other due to different preservatives.

Because only the inner hole is heated, the advantages of heating with high frequency heater: it can quickly, reliably and cleanly heat the rolling bearing to the required temperature. The attention of the outer side is very small, so it can be very easy to install the equipment on the shaft and into the seat hole.
