Tapered roller bearing refers to the radial thrust rolling bearing whose rolling element is tapered roller. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial load dominated by radial load, which is often used in double, reverse installation. The inner and outer seat rings can be installed separately, and the radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial load dominated by axial load, which is generally not used alone to bear the pure axial load. It can be used to bear the pure radial load when it is used as a pair configuration (the same end is installed relatively).

Tapered roller bearings Advantage:
1. High speed and high precision
2. Long service life
3. Lowest noise and good performance
Tapered roller bearings have conical inner ring and outer ring raceways, and tapered rollers are arranged between them. The projection lines of all conical surfaces converge at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact angle α Determined; α The larger the angle, the higher the axial load capacity. The angle is expressed by the calculation coefficient E; The larger the E value is, the greater the contact angle is, and the greater the applicability of the bearing to bear axial load is.
Tapered roller bearings are usually separable, that is, the tapered inner ring assembly composed of the inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring).

Tapping machine bearing Application：
Tapered roller bearings are widely used in machine tool spindles, gear reducers, automotive drive axles, transmissions, rolling mills, mines, metallurgical industries, plastic machinery, household appliances, motors, pumps, machinery and other automotive parts.
Tapping machine bearing Feature:
1. High load carrying capacity
The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
2. Accommodate misalignment
Tapered roller bearings are self-aligning and can accommodate misalignment .
3. Separable design
Tapered roller bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.
4. High speed capability
The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
5. Long service life
The tapered roller profile reduces edge stresses at the roller/raceway contact.
6. Low friction
The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.
