Structure And Characteristics Of Single Row Tapered Roller Bearing

Single row tapered roller bearing

The inner and outer rings of single row tapered roller bearings have tapered raceways, and the rollers are also tapered. If the cone is extended, its vertex intersects a point on the bearing axis. Therefore, the roller of tapered roller bearing can realize pure rolling on the raceway. Common tapered roller bearing models include Timken m224711, Timken l44640, Timken jhm33449, etc.

Structure And Characteristics Of Single Row Tapered Roller Bearing
Structure and characteristics

Single row tapered roller bearing is a separate bearing. The inner component of the bearing (composed of roller, cage and inner ring) and the outer ring can be separated. Therefore, it can be easily installed on the journal and bearing seat.

Tapered roller bearings are suitable for bearing radial load, unidirectional axial load and combined radial and axial load. The axial load capacity of tapered roller bearings depends on the contact angle α, outer race raceway angle, contact angle α. The larger the greater the axial load capacity. Single row tapered roller bearings can bear axial load in one direction. It can limit the axial displacement of the shaft in one direction relative to the bearing seat. Even under pure radial load, the tapered roller bearing will produce additional axial force. At this time, an equal amount of reverse force is needed to balance it. Generally, two single row tapered roller bearings with the same structure are installed face to face or back to back in two supports.

Application

Single row tapered roller bearings are widely used in automobiles, mining, metallurgy, plastic machinery and other industries.
