CE Customized OEM 10 22311 22315 22317 22318 22319pack Double Rubber Original Package Spherical Roller Bearings Original Bearing

The spherical roller bearing has a double row of rollers, the outer ring has a common 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 angle error is caused by the installation error or the shaft deflection. In addition to radial loads, the bearings can also withstand axial loads acting in both directions.

Spherical roller bearings have two types of inner holes: cylindrical and conical, and the taper of the conical taper hole is 1:30 and 1:12. This conical inner hole bearing is equipped with an adapter sleeve or a withdrawal sleeve. The tapered inner hole self-aligning ball bearing can be easily and quickly assembled on the optical shaft or the stepped machine shaft.

The models of spherical roller bearings are: spherical roller bearing (type 20000CC); spherical roller bearing with tapered hole (type 20000CCK); spherical roller bearing (type 20000CC/W33); spherical roller bearing with tapered hole (20000CCK/W33 type); Spherical roller bearing mounted on the adapter sleeve (20000CCK+H type); Spherical roller bearing mounted on the adapter sleeve (20000CCK/W33+H type) A total of 6 types. 

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.

Mainly applicable cage: stamped steel plate reinforced cage (suffix E, very few in China). Stamped steel 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 .
Spherical roller bearings are the rolling-element bearings that permit rotation with low friction, and permit angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.
