China Spherical Roller Bearing Spherical roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure enables it to have self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing box seat on the error or the shaft bending, and is suitable for the occasions where the installation error or the shaft deflection causes the angle error. In addition to radial loads, the bearings can also withstand axial loads acting in both directions. Spherical  the inner ring has no ribs and adopts steel plates. Stamping cage, CA type Trien bearing is characterized by ribs on both sides of the inner ring and the use of car-made solid cage. 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.
