Tapered roller bearing introduction-2 The ability of single-row tapered roller bearings to bear axial load depends on the contact angle, that is, the outer ring raceway angle. The more big angle, the more big axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills
The type code of tapered roller bearings is 30000, and tapered roller bearings are separable bearings. Normal in GB/T307.1-94 "Rolling Bearing Radial Bearing Tolerance", The outer ring and internal components of the bearing within the size range of the standard can be replaced with other bearings that meet the standard.
The angle of the outer ring, the diameter of the outer raceway and the outer dimensions and have been standardized. It is not allowed to change during design and manufacturing. As a result, the outer ring and inner components of the tapered roller bearing can be interchanged in all worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, the bearing loading capacity is large and the limit speed is low. Tapered roller bearings can withstand axial load in one direction and can limit axial displacement of the shaft or housing in one direction.
