INA bearing iron filings, burrs, dust and other foreign matter into will make rolling bearings in operation produce noise and vibration, and even damage the raceways and rolling elements. So, before installing the bearing, you must make sure that the mounting surface and installation environment clean.
Lubrication INA bearing operation and life are extremely important to you an overview of the general principles of selection grease. Grease base oil, thickener and additives made of different types and different brands of the same type of grease performance varied widely, the rotation limit allowed, important to note that in the choice. The performance of the grease is mainly determined by base oil, typically a low-viscosity base oil suitable for the application of low temperature, high speed, high viscosity at high temperature, high load. Thickener also relates to the lubricating properties, the water resistance of the the water resistance decision grease thickeners. In principle, the different brands of grease can not be mixed, Moreover, even if the same kind of grease thickener, also with each other because of different additives adversely affect.
1) Rolling the installation space can be accommodated in the rigidity and strength of the bearing type within the bearing installation space due to design shafting focus axis, it is generally first determine the major axis diameter, i.e. INA bearing diameter. But there are a variety of rolling bearings of dimension series and type, should choose the most suitable type of bearing.
2) the size, direction and nature of the load bearing load bearing load capacity with a basic load ratings, the values ??contained in the bearing size sheet rolling bearing load varied, such as the size of the load, only radial load, axial load is a unidirectional or bidirectional, vibration, or the degree of impact etc.. After considering these factors, again select the most suitable type of bearing.
3) Speed ??can adapt to the type of mechanical speed bearing [bearing speed limit value basis Limiting speed, the values ??set out in the the the bearing size table] INA bearing speed limit not only take on the bearing type is also limited to bearing size, cage type, precision level, load conditions and lubrication method, therefore, the choice must take into account these factors.
4) with the required rotational accuracy rotation accuracy bearing type dimensions and running accuracy of the bearing from GB bearing type standardized machine tool spindle, gas turbine and control machine requires high rotational accuracy, high speed and low friction, which should be used when more than five precision Rolling.
