1PCS Bearing 23138CC/W33 Spherical Roller Bearing self-aligning Roller Bearing Size 190 * 320 * 104mm

Spherical roller bearings have double row rollers, with one shared spherical raceway on the outer ring and two raceways on the inner ring tilted at an angle relative to the bearing axis. This clever construction gives it automatic centering performance, making it less susceptible to errors or shaft bending caused by the angle between the shaft and the bearing housing. It is suitable for situations where installation errors or shaft deflection can cause angle errors. This bearing can not only withstand radial loads, but also axial loads acting in both directions. Spherical roller bearings have two types of inner holes: cylindrical and conical. The conical taper hole has a taper of 1:30 and 1:12, respectively. This type of conical inner hole bearing can be easily and quickly assembled on the optical axis or stepped machine shaft with a tightening sleeve or a retraction sleeve. The models of self-aligning roller bearings include: self-aligning roller bearings (20000CC type); Conical hole self-aligning roller bearing (20000CCK type); Self aligning roller bearings (20000CC/W33 type); Conical hole self-aligning roller bearing (20000CCK/W33 type); Self aligning roller bearings (20000CCK+H type) installed on tight fitting sleeves; There are a total of 6 types of self-aligning roller bearings (20000CCK/W33+H type) installed on the tight fitting sleeve Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. Has high radial load capacity, especially suitable for working under heavy loads or vibration loads, but cannot withstand pure axial loads. The outer raceway of this type of bearing is spherical, so its centering performance is good and can compensate for coaxiality errors. There are two rows of symmetrical spherical rollers, with a shared spherical raceway on the outer ring and two raceways on the inner ring that are inclined at an angle to the bearing axis. They have good centering performance and can still be used normally when the shaft is bent under force or installed at different concentricity. The centering performance varies with the bearing size series, and the generally allowed centering angle is 1-2.5 degrees. This type of bearing has a large load capacity and can withstand axial loads acting in both directions in addition to radial loads. It has good impact resistance. Generally speaking, the working speed allowed for self-aligning roller bearings is relatively low

• During the use of self-aligning bearings, it is necessary to pay attention to lubrication and sealing to prevent dust and other pollutants from entering the interior of the bearing, which can affect its performance and lifespan. Regular inspection and maintenance can extend the service life of bearings and reduce the occurrence of faults
