Conical Roller Bearing Classification

The conical roller bearings belong to the separation bearings, and the inner and outer rings of the bearings have tapered raceways. These bearings are divided into different structural types, such as single-column, double-row and four-row conical roller bearings, according to the number of rollers installed. Single-row conical roller bearings can withstand radial and one-way axial loads. When the bearing is subjected to radial load, an axial force is generated, so when another bearing that can withstand the axial force in the opposite direction is required to balance it.

A single-column conical roller bearing has an outer ring, and an inner ring assembly with an inner ring of the inner ring and a set of tapered rollers, which is encased by a basket-shaped cage. The outer ring can be separated from the inner ring assembly, in accordance with the ISO conical roller bearing form factor standard, any standard model of conical roller bearing outer ring or inner ring assembly should be able to achieve international interchange with the same model outer ring or inner ring assembly. That is, the same model of outer ring in addition to external dimensions, tolerances to comply with ISO492 (GB307) regulations, the inner ring component saperhorn, component cone diameter, etc. must also comply with the relevant provisions of the interchange.

In general, the cone angle of the outer ring raceway of a single-row conical roller bearing is between 10 and 19 degrees, and can withstand the combined action of both axial and radial loads. The larger the cone angle, the greater the ability to withstand axial loads. The bearing of the large cone angle, with the rear code plus B, and the cone angle between 25 and 29 degrees, can withstand a largeaaxiogal load. In addition, a single-row conical roller bearing can adjust the size of the play during installation.

The outer ring (or inner ring) of the double-row conical roller bearing is a whole. Two inner ring (or outer ring) small end face is similar, there is a partition in the middle, the gap is by the thick thickness of the outer ring to adjust, but also can be used to adjust the thickness of the outer ring to adjust the double-row conical roller bearing pre-earning.

Four-row conical roller bearings, the performance of this bearing and double-row conical roller bearings are basically the same, but than the double-row conical roller bearings bear a larger radial load, the limit speed is slightly lower, mainly used for heavy machinery.

Multi-sealed double and four-row conical roller bearings, ZWZ provides long-life, multi-sealed double, four-row conical roller bearings. Personalize the new design of the bearing, change the traditional design method of the full-sealed bearing, adopt a new sealstructure combination of sealing and dust protection, improve the sealing effect and improve the sealing performance. The life of multi-sealed double and four-row conical roller bearings increased by 20% to 40% compared with open-type structural bearings, and the lubricant consumption was reduced by 80%.
