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.
Spherical roller bearing application areas:
Steel equipment, mining machinery, engineering machinery, papermaking machinery, wind turbines, working machinery, gear units, electric motors (motors), pumps and compressors, injection molding machines
