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.

The ability of single row tapered roller bearings to bear axial load depends on the contact angle, that is, the outer race raceway angle. The greater the angle, the greater the axial load capacity. Single row tapered roller bearings are the most widely used tapered roller bearings. Small size double row tapered roller bearings are used in the front wheel hubs of cars. Four row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
Structural features:
The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate bearing.
The angle of the outer ring and the diameter dimension of the outer raceway have been standardized as the same as the overall dimension. It is not allowed to change during design and manufacturing. So that the outer ring and inner components of tapered roller bearings can be interchangeable all over the world.
Tapered roller bearings are mainly used to bear the combined radial and axial loads dominated by radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or housing in one direction.

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.
