Four-row cylindrical roller bearings mainly bear combined radial and axial loads, which are mainly radial. The bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearances of double-row and four-row tapered roller bearings have been set at the factory according to user requirements and do not require user adjustment. Four-row cylindrical roller bearings have tapered inner and outer ring raceways, with tapered rollers arranged between the two. The projection lines of all the cone surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the angle α, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the greater the value of e, the greater the contact angle, and the greater the applicability of the bearing to bear the axial load. Four-row cylindrical roller bearings are usually separated, that is, the tapered inner ring component composed of the inner ring with roller and cage components can be installed separately from the tapered outer ring (outer ring). Four-row cylindrical roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
