Spherical Roller Bearing

The spherical roller bearing has double-row rollers, a common spherical raceway on the outer ring, and two raceways on the inner ring that are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have self-aligning performance, so it is not easily affected by the angle error between the shaft and the bearing box seat or the shaft bending, and is suitable for occasions where the angle error is caused by installation error or shaft deflection. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads.

Spherical Roller Bearings Features

1.Automatic self-aligning performance‌: The outer ring raceway of the spherical roller bearing is spherical, with good self-aligning performance, which can compensate for coaxiality errors and achieve automatic self-alignment.

‌2.Load bearing capacity‌: This type of bearing can withstand large radial and axial loads, and is particularly suitable for working under heavy loads or vibration loads, and has good impact resistance.

‌3.Structural features‌: The rollers and raceways of spherical roller bearings have a high degree of fit, severe relative sliding, and large friction, so the allowable operating speed is low.

‌Application scenarios‌

Spherical roller bearings are widely used in mechanical equipment with heavy loads and vibration conditions such as papermaking machinery, reduction gears, railway vehicle shafts, and rolling mill gearbox seats.
