NSK tapered roller bearing

The tapered roller is assembled in the bearing as a rolling element and guided by the large gear edge of the inner ring. It can bear radial load and axial load in one direction, with large load capacity. As a high load capacity bearing, there are HR series to increase the size and number of rollers.
Like the centripetal thrust bearing, the two bearings are generally used opposite. In this case, it can be adjusted in the axial direction according to the spacing of the same kind of inner ring or outer ring to obtain the set clearance.
Because it is a separate type, the inner ring and outer ring can be removed respectively.
Due to the different size of contact angle, it can be divided into general cone angle shape, medium cone angle shape and large cone angle shape. According to the number of rows of rollers, it can be divided into double row and four row tapered roller bearings. Generally, steel plate is used to punch the cage.
Metric series tapered roller bearing
For metric series medium cone angle bearings and large cone angle bearings, the contact angle codes C and D are recorded after the inner diameter code respectively. Ordinary tapered angle bearings are not marked with contact angle code. Medium tapered angle bearings are mainly used for pinion shafts of automobile differential devices.
In the HR series with high load capacity, for the bearing with basic code marked J, its outer ring width, small end face diameter of outer ring raceway and contact angle are consistent with the provisions of ISO. Therefore, the inner ring assembly (cone) and outer ring of the bearing with the same basic code marked with this code are interchangeable.
