GCr15 bearing steel is a high-carbon chromium bearing steel with less alloy content,  good performance, and is the most widely used. After quenching and tempering, it has a high and uniform hardness, good wear resistance, and high contact fatigue performance.

Classification of tapered roller bearings：

According to the number of rows of rolling elements in the bearing, it is divided into single-row, double row, and four-row tapered roller bearings.

Single row tapered roller bearing

Double row tapered roller bearing

Four row tapered roller bearing

Features of tapered roller bearings:

The ability of single-row tapered roller bearings to bear axial load 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 machineries such as large cold and hot rolling mills.
