1.The Structure Type of Spherical Roller Bearing:

Spherical roller bearings divided into: cylindrical bore, tapered bore.Tapered bore taper 1:12, respectively, after the code for the K-aligning roller bearings and 1:30 post code for the K30-aligning roller bearings. Such bearings and shaft with a conical, axial movement of the inner ring of the bearing can be adjusted radial clearance.

2.The Features of Spherical Roller Bearing:

Spherical roller bearing also known as self-aligning roller bearing. Spherical roller bearings have two rows of rollers. This bearing mainly accommodate the radial load, and can accommodate the axial load from one direction at the same time, but not accommodate the pure axial load. Sherical roller bearings have very good loading capacity, especially for hevey load or vibrational load.
Spherical roller bearing use staming steel cage (the suffixed "E"), glass-fibre reinforced polyamide cage (the suffixed "TVPB") or machined brass cage (the suffixed "M") or stamping steel cage for vibratory applications (the suffixed JPA).
Spherical roller bearings mainly used to papermaking machinery, speed reducer, cruser, etc.

3.The Application of Spherical Roller Bearing:

Papermaking machinery, deceleration device, railway vehicle axle, rolling mill gear box bearing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical seat-aligning bearing.

4.The Basic Parameters of Spherical Roller Bearing:

Spherical roller bearings with two rollers, mainly bear radial load, but also can withstand axial load in either direction. A high radial load capacity, especially suitable for heavy work loads or vibration, but can not afford pure axial load. This kind of bearing outer ring raceway is spherical shape, so its good aligning performance, can compensate concentricity error.
There are two symmetrical spherical roller outer ring of a common spherical raceway, the bearing inner ring with two axis tilt
Angle of raceway, aligning with good performance, when the shaft bending stress or install a different heart still bearing the normal use, tune concentric with the bearing size series vary, generally allow aligning angle is 1 to 2.5 degree load bearing capacity of the larger type, in addition to radial loads but also under way outside the role of bearing the axial load, with good impact resistance, in general, self-aligning roller bearings allowed working speed than the low.
