What is the purpose of the bearing? Source: bearing | last updated: - 2020 06 - What is the purpose of the 30 bearing? Bearing USES: 1, single row bearing widely used, is separated type, suitable for high speed, add grease seal design does not need maintenance, can bear radial load, can also carry axial load, commonly used for motor, reducer, electric tools, air conditioning, etc. 2. The ball bearing, ball gap gap of bearing inner ring and outer ring each have a ball gap, more than the standard products can accommodate and larger ball, and have higher radial bearing capacity, but its axial load capacity is small, special bearing bearing rotating speed is lower than standard bearings. It is mainly used in automobile gearbox and heavy rotation at low speed application. 3. The material is not stainless steel stainless steel bearing, can resist the corrosion of water and other medium, it is mainly used for corrosion environment, the food industry, etc. 4. Double row bearing design and special product structure is very similar, but only one line. In addition to the radial load, it can also carry two-way axial load. The use of single bearing to bear load. Bearing configuration. 5. Products are usually under high temperature, clearance is bigger, is four times that of C5 clearance. Consult Enmubi technical personnel, the technical personnel in the - 40 - + 250 degrees the temperature range of use. To sum up, the use of the bearing is mainly used for: automobile, machine tools, household appliances, motor, pump, agricultural machinery, textile machinery, food industry, etc. , its output accounts for more than half of the whole bearing production, this is the price of a good performance, large output, a wide range of bearings. Bearing radial clearance of the bearing clearance analysis is divided into the original clearance, clearance and installation work clearance. Often the original bearing radial clearance is greater than the bearing clearance at work. Clearance is one of the important technical parameters of the bearing, it directly influence on the performance of the bearing technology, such as load distribution, vibration, noise, friction, and service life of mechanical motion precision. Strictly speaking, the dynamic load rating of bearing will changes with the size of the clearance. The rated load (listed in the catalogue C and C0) Is the work load value of the gap is zero. If the clearance is too large, the bearing internal bearing area will reduce, on the surface of the rolling contact stress increases, the movement of the bearing will reduce the accuracy, vibration and noise will increase, the service life of the bearing will be shortened. In the process of operation, and may even lead to bearing 'bite'. Therefore, depending on the type of bearing and working conditions to select different levels of the bearing clearance is very important. Bearing internal clearance to C2, standard ( CN） , C3, C4 and C5, met GB4604.
