Spherical roller bearings are between the inner ring with two raceways and the outer ring with spherical races; the bearings are equipped with drum rollers. The middle of the curvature of the raceway surface of the outer ring is common with the bearing; therefore, The same self-aligning function of the active self-aligning ball bearing. When the shaft and the outer casing are flexed; it can be actively adjusted; the shaft is not added. The spherical roller bearing can accept the radial load and the axial load in two directions. Radial The load can be large; it is suitable for heavy load and impact load conditions. The inner ring inner diameter is the bearing of the tapered hole; it can be directly installed. Or use the tightening sleeve and the dismantling cylinder device on the cylindrical shaft. The cage uses the steel plate stamping cage. , polyamide forming cage and copper alloy car cage.
Spherical roller bearings can accept large radial loads; they can also accept a certain axial load. The outer ring raceways of this type of bearings are spherical in shape; therefore, they have a aligning function; when the shaft is subjected to bending or skewing, When the middle line of the inner ring and the middle line of the outer ring are not inclined more than 1° to 2. 5°, the bearing can still work.
Spherical roller bearings are suitable for receiving heavy loads and impact loads; widely used in metallurgy, rolling mills, mining, petroleum, paper, cement, sugar and other occupations.
