CA type self-aligning roller 3

Self-aligning roller bearings have dual row rollers, the outer ring has one common spherical raceway, and the inner ring has two raceways that are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have automatic centering performance, which is not susceptible to the influence of the angle between the shaft and the bearing housing seat on errors or shaft bending. It is suitable for situations where installation errors or shaft deflection cause angular errors. The bearing can withstand both radial and axial loads acting in both directions. Self-aligning roller bearings have two types of inner holes: cylindrical and conical, with conic taper of 1:30 and 1:12. This type of tapered inner hole bearing is equipped with a locking sleeve or a withdrawal sleeve, which allows for convenient and rapid assembly of the tapered inner hole self-aligning ball bearing on an optical shaft or a stepped machine shaft. Self-aligning roller bearings are mainly used in paper making machinery, speed reduction devices, railway vehicle axles, steel rolling machine gear box bearing seats, steel rolling machine rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial speed reducers, and vertical belt seat self-aligning bearings.
