In order to improve the lubrication of the bearing, the spherical roller bearing with an annular oil groove and three oil holes in the outer ring can be provided to the user, which is represented by the bearing rear code /W33. Spherical roller bearings with inner ring oil holes can also be supplied according to the user's requirements. In order to facilitate customer loading, unloading and replacement of bearings, spherical roller bearings with tapered inner holes can also be provided. The taper taper is 1:12 , It is represented by the post code K. In order to meet the requirements of special users, bearings with an inner hole taper of 1:30 can also be provided, and the post code is K30. Bearings with a tapered inner hole can be directly mounted on the tapered journal with a lock nut, or mounted on a cylindrical journal with the help of an adapter sleeve or a withdrawal sleeve. In order to ensure that the bearing prevents harmful slippage between the raceway and the roller due to centrifugal action when the bearing is running at high speed, the bearing should bear a certain minimum radial load, which can be estimated as follows: Fr =0.02C where: Fr -- minimum radial load N C鈥攖he basic dynamic load rating N of the bearing Equivalent Dynamic Load P=Fr+Y1Fa when Fa/F e P=0.67Fr+Y2Fa when Fa/F e where: P鈥攅quivalent dynamic load N Y1 Y2鈥攁xial dynamic load factor Equivalent static load P0=Fr+Y0Fa where: P0鈥攅quivalent static load N Y0鈥擜xial static load factor Structural classification structure type Spherical roller bearings are divided into: cylindrical bore, conical bore. The taper of the tapered inner hole is 1:12 for the rear-mounted spherical roller bearing (type 153000 or 113000) with the rear code K30 and the 1:30 rear-mounted spherical roller bearing with the code name K30. When this type of bearing is matched with a conical shaft, the radial clearance of the bearing can be adjusted by moving the inner ring in the axial direction. Postcode Install the tapered hole spherical roller bearings with the rear code K and K30 on the matching adapter sleeve, and then become the rear code K+H type and K30+H type bearings. This kind of bearing can be installed on the optical shaft without shoulder, and is suitable for occasions where the bearing needs to be installed and removed frequently. In order to improve the lubricating performance of the bearing, there is an annular oil groove on the outer ring of the bearing and three evenly distributed oil holes are drilled, and the rear code is W33. Use and installation Mainly applicable cage: stamped steel plate reinforced cage (suffix E, very few in China). Stamped steel plate cage (suffix CC), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined brass two-piece cage (suffix MB). Machined brass integral cage (suffix CA), stamped steel cage for vibration applications (suffix JPA). Brass cage (suffix EMA) for vibration applications. For the same structure, the code on the bearing may be different. Main uses: papermaking machinery, reduction gear, railway vehicle axles, rolling mill gearbox bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings with seats . Install Spherical roller bearings are equipped with drum-shaped roller bearings between the inner ring with two raceways and the outer ring with spherical raceways. This method can be used. 2. Electric furnace heating method Put the bearing in a closed automatic temperature-controlled electric furnace for heating, the heating is uniform, the temperature control is accurate, the heating is fast, and it is suitable for heating many bearings in a batch. 3. Induction heating method The use of induction heaters can quickly, reliably and cleanly heat the spherical roller bearing to the required temperature, which is especially suitable for occasions where the inner ring is tightly fitted, because only the inner ring is heated, and the outer ring is heated. The ring is less heated, which makes it easier to install on the shaft and into the seat hole. 4. The light bulb heating method uses a 50W light bulb to heat the spherical roller bearing, which can ensure that the heating temperature is about 100 掳 C. The smaller bearing can be placed directly on the bulb, and the larger bearing can be placed in the cone of the bulb. The cover can prevent the heat loss of the bulb, and make the heating uniform. The conical cover can be adjusted up and down, and can be adapted to heat bearings of different sizes within a certain range. If far-infrared light bulbs are used, pay attention to the direction of the light bulbs, so as to avoid infrared rays being harmful to people. This kind of light bulb can be used for energy-saving light bulb heating method, which is suitable for a small number and is not often needed; where the bearing needs to be heated, the light bulb can also be used for lighting at ordinary times, and no other equipment is required. 5. Oil tank heating method This is a widely used traditional heating method. A metal mesh is installed at a distance of 50~70mm from the bottom of the oil tank, and the bearing is placed on the mesh. website:http://www.bearingssuppliers.com/spherical-roller-bearing/
