The tapered roller bearing belongs to the separated type bearing, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types based on the number of rows of installed rollers, such as single row, double row, and four row tapered roller bearings. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to radial load, an axial force will be generated, so another bearing capable of withstanding opposite axial forces is needed for balance.

The cone angle of the outer race of a single row tapered roller bearing is between 10 ° and 19 °, and it can withstand both axial and radial loads simultaneously. The larger the cone angle, the greater the ability to withstand axial loads. A bearing with a large cone angle, with a suffix B and a cone angle between 25 ° and 29 °, can withstand large axial loads. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.

The outer ring (or inner ring) of a double row tapered roller bearing is a whole. The two inner (or outer) rings have similar small end faces and a spacer ring in the middle. The clearance is adjusted by the thickness of the spacer ring, or the pre interference of the double row tapered roller bearing can be adjusted by the thickness of the spacer ring.

Four row tapered roller bearings have the same performance as double row tapered roller bearings, but they bear greater radial loads and slightly lower limit speeds than double row tapered roller bearings. They are mainly used in heavy-duty machinery.

We offer long-life, multi sealed double and four row tapered roller bearings. Personalized and brand new design of bearings, changing the traditional design method of fully sealed bearings, adopting a new sealing structure combining sealing and dust prevention to improve sealing effectiveness and enhance sealing performance. Compared with open structure bearings, the lifespan of multi sealed double and four row tapered roller bearings is increased by 20% to 40%; Reduce lubricant consumption by 80%.

Conical roller bearings are widely used in industries such as automobiles, rolling mills, mines, metallurgy, and plastic machinery.
