Tapered roller bearings belong to separate type bearings. Both inner and outer rings of bearings have tapered raceways. The bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rollers installed.

Taper Roller Bearing

Tapered roller bearings are radial thrust rolling bearings with tapered rollers. There are two kinds of small cone angle and big cone angle. Small cone angle mainly bears radial and axial combined loads mainly consisting of radial loads. It is often used in two ways, reversed installation, inner and outer seat rings can be installed separately, and radial and axial clearance can be adjusted in installation and use. Large cone angle mainly bears axial and radial combined loads mainly consisting of axial loads, generally not used alone to bear pure axis. Directional load, as a pair of configurations (relative installation of the same name end), can withstand pure radial load.

Classification

Single row tapered roller bearings have an outer ring, and its inner ring and a group of tapered rollers consist of an inner ring assembly enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing profile size standard, the outer ring or inner ring assembly of any standard tapered roller bearing should be able to achieve international interchange with the same type of outer ring or inner ring assembly. That is to say, the outer ring of the same type should conform to the requirements of ISO492 (GB307), and the cone angle and cone diameter of the inner ring assembly must also conform to the requirements of interchange.

Usually, the conical angle of the outer raceway of single row tapered roller bearings is between 10 ~19, which can bear the combined action of both axial and radial loads. The bigger the cone angle is, the greater the ability to withstand the axial load is. Bearings with large taper angle, with rear code plus B, and taper angle between 25 ~29, can withstand large axial loads. In addition, single row tapered roller bearings can adjust the clearance during installation.

The outer ring (or inner ring) of double row tapered roller bearings is a whole. Two inner rings (or outer rings) have similar small end faces. There are spacers in the middle. The clearance is adjusted by the thickness of spacers. The thickness of spacers can also be used to adjust the pre-interference of double row tapered roller bearings.

Four-row tapered roller bearings have the same performance as double-row tapered roller bearings, but they bear larger radial load and lower limit speed than double-row tapered roller bearings. They are mainly used in heavy machinery.

Multi-sealed double-row and four-row tapered roller bearings, ZWZ provides long life, multi-sealed double-row and four-row tapered roller bearings. New personalized design of bearings is carried out. The traditional design method of fully sealed bearings is changed. A new type of sealing structure combined with sealing and dust prevention is adopted to improve the sealing effect and seal performance. Compared with open structure bearings, multi-seal double-row and four-row tapered roller bearings have 20%-40% longer service life and 80% lower lubricant consumption.
