Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have 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.

Classification
A single row tapered roller bearing has an outer ring, an inner ring and an inner ring assembly consisting of a set of tapered rollers enclosed by a basket cage.
The conical Angle of the outer ring raceway of a single row tapered roller bearing is between 10° and 19°, which can withstand the combined action of axial load and radial load at the same time. The larger the cone Angle, the greater the ability to bear axial load. Bearings with large tapered angles, rear code plus B, cone Angle between 25°~29°, it can bear large axial load. In addition, 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 small end faces of the two inner rings (or outer rings) are similar, and there is an interval ring in the middle. The clearance is adjusted by the thickness of the interval ring, and the thickness of the interval ring can also be used to adjust the pre-interference of double row tapered roller bearings.
Four row tapered roller bearings, this kind of bearing performance and double row tapered roller bearings are basically the same, but than double row tapered roller bearings bear greater radial load, the limit speed is slightly lower, mainly used in heavy machinery.

FAQ
1How to install tapered roller bearings?
Adjusting axial clearance For the installation of tapered roller bearing axial clearance can be adjusted by adjusting nuts on the journal, adjusting gaskets and threads in the bearing seat hole, or by pre-tightening springs and other methods. The size of axial clearance is related to the arrangement of bearing installation, the distance between bearings, the material of shaft and bearing seat, and can be determined according to working conditions.
For tapered roller bearings with high load and high speed, the influence of temperature rise on axial clearance must be considered when adjusting clearance, and the reduction of clearance caused by temperature rise must be estimated. That is to say, the axial clearance should be properly adjusted to a larger extent.
For bearings with low speed and bearing vibration, no-clearance installation should be adopted, or pre-load installation should be applied. The purpose is to make the tapered roller bearing roller and raceway have good contact, uniform load distribution, prevent the roller and raceway from vibration impact damage. After adjustment, the size of axial clearance is tested with a micrometer.
2What are the basic performance requirements for the configuration of KOYO double row tapered roller bearings?
The basic performance requirements of koyo bearings on materials depend on the working characteristics of double row tapered roller bearings. Generally speaking, bearing steel should have the following properties:
1. High contact fatigue strength.
2. High wear resistance.
3. High elastic limit and yield strength.
4. High and uniform hardness.
5. Certain impact toughness.
6. Good dimensional stability.
7. Good corrosion inhibition performance.
8. Good process performance.
3If this kind of bearing is used improperly, are there any precautions?
(1) Keep tapered roller bearings and their surroundings clean.
Even small dust that can't be seen by the eye will bring bad effects to the bearing. Therefore, keep the surrounding clean, so that the dust will not invade the bearing.
(2) Use with care and caution.
Strong impact on tapered roller bearings in use will produce scars and indentations, which will become the cause of accidents. In serious cases, there will be cracks, fracture, so must pay attention to.
(3) Use the appropriate operating tools.
Avoid replacing existing tools with the right ones.
(4) Pay attention to the corrosion of tapered roller bearings.
When operating bearings, sweat on the hands will become the cause of rust. Be careful to use clean hands, preferably wear gloves as much as possible.
