How much do you know about bearing taper roller?

The tapered rollers are assembled in the bearing as rolling elements and guided by the large rib 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 taper roller, there is the HR series with increased roller size and number of rollers.

Like the radial thrust bearing, two bearings are generally used oppositely. In this case, it can be adjusted in the axial direction according to the interval of the inner ring or outer ring of the same type to obtain the set clearance.
Because it is a separate type, the inner ring and outer ring can be disassembled separately.

Due to the different size of the contact angle, it is divided into general cone angle, medium cone angle, and large cone angle. The number of roller rows can be divided into double row and four row tapered roller bearings. Generally, steel stamping cages are used.

Metric series bearing taper roller

For medium taper angle bearings and large taper angle bearing taper roller of the metric series, the contact angle codes C and D are respectively recorded after the inner diameter code. Ordinary cone angle bearings are not marked with contact angle codes, and medium cone 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.

This type of bearing taper roller is commonly used in:
Wheel hubs for light, industrial and agricultural vehicles
Transmission (gearbox and differential)
Machine tool spindle
