Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.

A single-row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are enclosed by a basket cage into an inner ring assembly, and the outer ring and the inner ring assembly can be separated. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

The range of four-row tapered roller bearings is wide, including not only the traditional design with an intermediate ring between the outer ring and/or the inner ring, but also the modification of the four-row tapered roller bearings with an integrated middle ring and the bearing ring.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.2377000900

1) Less coefficient of friction, High limiting speed, Large size range, Variations of structure.2) Tapered Roller Bearings are designed such like cup. Cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.3) Single-row tapered roller bearing is able to carry radial and axial load in one directionssimultaneously because an axial component of produced when this type of bearings loadedradically, two bearings are used together facing one another, or two or more bearings arematched and used.

Four row tapered roller bearings are mainly used for work rolls, support rolls, and billet breakers of various plate and strip rolling mills. The clearance of the bearing is changed by adjusting the thickness of the spacer to make it more suitable for the working condition.1. Strong bearing capacity: four row tapered roller bearings can withstand greater loads under the same size, because it is shared by multiple rollers, so it has higher carrying capacity and better distribution performance.2.

Double-row tapered roller bearings have many advantages in structure and performance, so they are widely used in industrial production.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)302027202E15351114.913.412000160000.053302037203E17401220.821.89000120000.079302047204E20471428.230.58000100000.126302057205E25521532.237700090000.154302067206E306217.543.250.5600075000.231302077207E35721754.263.5530067000.331302087208E4080186374500063000.422302097209E45851967.883.5450056000.474

UBC tapered roller bearing is a kind of rolling bearing with tapered roller, the roller and raceway between the inner ring (cone hub) and the outer ring (cup) intersect at the cone half Angle on the outer surface of the cone, so that the bearing can bear a large load in the radial and axial direction. UBC tapered roller bearings usually include single row, double row and four row structures, which are widely used in automotive, mechanical equipment, aerospace and other fields.

Truck hub units, which contain two tapered roller bearings, are pre-adjusted, greased and sealed at the factory in order to simplify installation. The wheel bearing units are intended for use in truck, trailer and buses.
