    Self-aligning ball bearing

    Self-aligning ball bearing: The inner ring of the two raceways and the raceway are between the outer rings of the spherical surface, and the bearings are fitted with drum rollers. The center of curvature of the raceway surface of the outer ring is identical to the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and outer casing are deflected, it can be adjusted automatically without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. The radial load capacity is large, and it is suitable for heavy load and impact load. The inner ring inner diameter is a tapered bore bearing that can be mounted directly. Or use the adapter sleeve and the removal cylinder to mount on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy cage.

    Self-aligning ball bearings can withstand large radial loads while also withstanding certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has the function of self-aligning. When the shaft is bent or tilted so that the center line of the inner ring and the center line of the outer ring are inclined no more than 1°~2.5°, the bearing can still work. .

    The inner diameter of the self-aligning ball bearing has two kinds of cylindrical and conical shapes. The conical inner bore has a taper of 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three evenly distributed oil holes are machined on the outer ring of the bearing.
