Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious construction makes it self-aligning and therefore not susceptible to axial or bearing housing angle errors or shaft bending. It is suitable for installation errors or shaft deflections that cause angular errors. In addition to being able to withstand radial loads, the bearing can withstand axial loads in both directions.
Spherical roller bearings have a cylindrical shape and a conical shape. The conical tapered bore has a taper of 1:30 and 1:12. The conical inner bore bearing is equipped with an adapter sleeve or a withdrawal sleeve. The tapered bore self-aligning ball bearing can be easily and quickly assembled on the optical axis or step machine shaft.
Mainly suitable cage: ram-plate reinforced cage (suffix E, few in China). Stamping 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 cage (suffix JPA) for vibration applications. Brass cage (suffix EMA) for vibration applications. With the same structure, the bearing code may be different.
Main USES: papermaking machinery, reducer, railway vehicle axle, rolling mill gear box bearing seat, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical with seat adjustable bearing.
