Metric series tapered roller bearings
For medium taper angle bearings and large taper angle bearings of the metric series, the contact angle codes C and D are respectively recorded after the inner diameter code. Ordinary taper angle bearings are not marked with contact angle codes, and medium taper angle bearings are mainly used for pinion shafts of automobile differential devices.
In the high-load capacity HR series, bearings with the basic code marked J, the outer ring width, outer ring raceway small end surface diameter and contact angle are consistent with ISO regulations. Therefore, the inner ring assembly (CONE) and outer ring of the same basic code bearing marked with this code are internationally interchangeable.
Among the tapered roller bearings of the metric series specified by ISO355, there are new sizes that are not based on the 3xx size series used in the past. Some of them are listed in the size table. The width of the outer ring, the diameter of the small end face of the outer ring raceway and the contact angle are consistent with ISO regulations, and the inner ring components and outer ring are internationally interchangeable.

Tapping machine bearing have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.
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.
