If the bearing is subjected to radial and axial forces at the same time, it is necessary to select the appropriate bearing according to the actual situation, then which bearings can bear both radial and axial forces at the same time?
1、 Self-aligning roller bearing
Spherical Roller Bearings
Self-aligning roller bearings can be divided into R type, RH type, RHA type and SR type according to the structure. The arc center of the outer ring raceway is consistent with the center of the bearing, with self-aligning performance, and can cope with the working conditions with large radial load and heavy load and impact load.
2、 Deep groove ball bearing
The cross section of the ring of the deep groove ball bearing is generally about 1/3 of the circumference of the equator of the sphere, and it is a continuous groove raceway. It mainly bears radial load force and can bear certain axial load. Because after its radial clearance increases, it can also have the properties of angular contact ball bearing. It is the most widely used bearing with small friction, high speed and precision.
3、 Cross roller bearing
The rollers of the cross roller bearing are arranged vertically with each other through the spacing retainer, so it can well withstand the radial load, axial load and torque load. The design of roller in 90 ° V shape enables the cross roller bearing to bear large loads in radial load, axial load and torque load.
4、 Tapered roller bearing
Tapered roller bearing is a separable type bearing, which has tapered raceways in both inner and outer rings. According to the number of roller rows, tapered roller bearings can be divided into single-row, double-row and four-row tapered roller bearings.
5、 Angular contact ball bearing
The inner and outer race raceways of angular contact ball bearings can carry out relative displacement on the horizontal axis. Therefore, they can bear both radial and axial loads, and angular contact ball bearings can work at higher rotational speeds. The larger the contact angle, the higher the axial load they can bear.
