Spherical roller bearings have double-row rollers, the outer ring has a common spherical raceway, the inner ring has two raceways, and is inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easily affected by the angle of the shaft and the bearing box seat to the error or the bending of the shaft. In addition to bearing radial loads, this bearing can also support axial loads in both directions.
Spherical roller bearings have cylindrical and conical internal bores, and tapered cone bores have a taper of 1:30 and 1:12. This tapered inner bore bearing is equipped with an adapter sleeve or a withdrawal sleeve The conical inner hole self-aligning ball bearing can be easily and quickly assembled on the optical axis or the stepper shaft.
Spherical roller bearings are divided into: cylindrical inner hole and conical inner hole. The tapered inner bores have a taper of 1:12, and a spherical roller bearing (type 153000 or 113000) with a rear designation of K, and a spherical roller bearing with a code of K30, 1:30. When this type of bearing is matched with a conical shaft, the inner ring moves in the axial direction to adjust the radial clearance of the bearing.
Mainly applicable cages: stamped steel reinforced cages (suffix E). Stamped steel plate type cage (suffix CC), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined brass two-piece cage (suffix MB). Machined brass monolithic cage (suffix CA), stamped steel plate cage (suffix JPA) for vibration occasions. Brass cage (suffix EMA) for vibration applications. The code on the bearing may be different for the same structure.
Main uses: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gear box bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical self-aligning bearings .
