Detail

The spherical roller bearing can bear heavy load, and with self-aligned function.

Two rows spherical rollers are put between the spherical raceways on the outer ring and the two grooves on the inner ring for spherical roller bearings. Since the curve center of outer ring is the same as that of the whole bearing arrangement, these bearings are self-aligned and automatically adjust the bending of the shaft and housing, besides, it can also compensate the concentricity erro caused by this. Except radial load, these bearings can also carry combination of axial and radial load in two directions and posess high load capacity as well as good resistance to vibration and impact.

Spherical roller bearings are mainly applied to metallurgic machinery, mining machinery, papermaking, vessel, textile machinery, coal mill, electrica power and other kinds of mechanical equipements. They are the bearings that are mostly widely used in machanical industry.

Product types

Cylindrical hole spherical roller bearing

According to the rib and cage, there are three types: CA, CC and MB

CA type: there are two small ribs on the two ends of inner ring, there is no rib in the middle, the cage is integral structure, the material is copper or carbon steel. This structure is mainly used  large-scale bearing and super-huge type bearing. The inner ring of C type is not big, small rib, cage is steel plate stamping cage. the length of roller add, the rated load increase. It also has high limit speed and low frictional loss. MB structure is asymmetrical cage, there is rib on the raceway of inner ring. This structure can bear heavy axial and radial load.

Tapered hole spherical roller bearing

The feature is the same with cylindrical hole spherical roller bearing, the inner hole is tapered hole, the nominal tapered degree is 1:12, the model add K.

But the taper degree of 240 and 241 series is 1:30, the model add K30. The tapered hole bearing can install on the tapered shaft by nut.

Vibrition screen spherical roller bearing

The new type vibration resistance spherical roller bearing are new structure developed for vibration machinery, which also used in normal equipment. The performance as followed: high load, impact resistance, vibration resistance, small friction, slow temperature rising, long service life.

The inner ring with fixed middle rib, can bear axial force. the cage adopt special structure, the inner and outer diameter two-way guide, control the guide clearance.

Split spherical roller bearing

This type is mainly used in applications where it is difficult to touch bearings or separable bearings are used and a big broken down cost caused by plenty of time and human maintenance or changing parts. For example, bent axle and long shaft. We can manufacture different structures of split spherical roller bearings according to customer's demands. In order to meet the requirements of mounting, the split inner rings and outer rings are normally adopted. The jamming rings on the two sides of wide inner rings make the mounting easy.
