Bearings are industrially manufactured support structures for connecting various parts. Different parts have different structures, so many different types of bearings have been developed. The following introduces the characteristics of tapered roller bearings:


1. Structural characteristics of tapered roller bearings

The top of the tapered roller bearing is equipped with a tapered roller, which is a bearing unit composed of radial rollers and components. The inner and outer rings of the bearing have tapered raceways. Since the cross-sectional diameter of the roll is short, but the length is long, it is named tapered roller bearing according to the shape.

2.The characteristics of tapered roller bearings

Although the section diameter of this part is very short, the size and weight of the part itself are relatively small, but its radial structure is compact and has a high load capacity, so its inner diameter size and load capacity are compared with other types of bearings, the outer diameter Small, especially suitable for the size constraints of radially mounted support structures.

On the other hand, the raceway of the outer ring of the bearing also plays a big role: the load capacity of the bearing is increased by increasing the angle of the contact surface.

In addition, the tapered roller bearing has high machining accuracy and high surface hardness, so it can withstand several times more force than its bearing force. Safe to use, tight connection and good performance.

The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, that is, the angle of the outer ring raceway. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.
