Tapered roller bearings are separable bearings, bearing inner and outer rings with tapered raceways line. These bearings are mounted on roller rows into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can bear radial load and axial load in one direction. When the bearing radial load

Select an important factor in fat
koyo bearings during operation, oil seal is required to maintain LNSERTED ball bearings and lubricants from external contamination barrier. Whether debris or moisture can not penetrate the bearings, to avoid causing its destruction. Home for the correct device bearing the longest life is to play an important factor. At the same time, must pay attention to the cleanliness of the Stainless steel slewing bearing bearing selection is correct and the choice of appropriate equipment and maintenance tools. In addition, the bearing must be to protect against contaminants and moisture contamination, and by means to ensure the correct and lubrication. Therefore, the design of the bearing with the column, the status of seals, lubricant type and lubrication cycle, and even a dedicated home for all the same plays and important role.
4 Mixed grease
If two incompatible greases, oils should never be incompatible mix. Usually its consistency becomes soft, it may eventually cause the loss due to grease easily LNSERTED ball bearing damage. If you do not know what kind of bearing grease previously used, then you must first completely remove the old grease bearing inner and outer, before adding new grease.
5 Classification of grease
Consistency of grease and lubricating ability is affected by the operating temperature of a temperature koyo bearings must operate at the same temperature to select the correct consistency and good grease lubrication. Fat in a different temperature range to produce a substantially low temperature can be divided into, and the high temperature with the temperature of the grease. Meanwhile, the main distinction according to the temperature and working conditions: oil according to its permissible operating temperature classification. There is a class of fats known resistance to crushing or resistance to crushing and adding molybdenum disulfide, and wherein lubricant with additives to enhance the strength of the film.
6 Select an important factor in fat
Choose a grease, if the wrong choice koyo bearing grease is all preventive measures to be futile. Base oil viscosity at operating temperature to provide sufficient lubrication effect is very important to the viscosity of the main affected by temperature, and decreases as the temperature, when the temperature drop is increased. Therefore, it is necessary to know the operating temperature of the base oil viscosity. Machinery manufacturers usually specify the use of certain oils, greases, however most of the specifications are very wide scope of application
