Self-aligning ball bearings are bearings with spherical balls between the inner rings of two raceways and the outer rings with spherical raceways.
The curvature center of the outer race raceway surface is consistent with the bearing center, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and shell are deflected, it can be automatically adjusted without increasing the bearing burden. Self-aligning roller bearings can bear radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy load and impact load. Bearings with tapered inner diameter can be installed directly. Or install it on a cylindrical shaft by using a tightening sleeve and a dismounting cylinder. Cage uses steel plate stamping cage, polyamide forming cage and copper alloy turning cage.
Self-aligning ball bearing Application:
Self-Aligning ball bearings to withstand heavy load and impact load , precision instruments, low noise motors, automobiles , motorcycles, metallurgy , rolling mill , mining, petroleum , paper, cement , sugar and other industries , and general machinery.
