Self-aligning roller bearing: The inner ring of the two raceways and the outer ring of the spherical raceway are equipped with spherical ball bearings. The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same aligning function as the automatic aligning ball bearing. When the shaft and shell are flexed, they can be adjusted automatically without increasing the bearing burden.

Product features
Mainly bear radial load, while can bear small axial load. The axial displacement of the shaft (shell) is limited in the clearance limit, with automatic aligning performance, allowing the inner and outer relative tilt is not much normal work, suitable for the supporting seat hole can not strictly ensure the coaxiality of the parts.

Self-aligning roller bearing has two kinds of structure, cylindrical hole and conical hole, cage material is steel plate, synthetic resin, etc. It is characterized by the spherical raceway of the outer ring, with automatic centering, which can compensate for the error caused by the concentricity and shaft deflection, but the relative inclination of the inner ring and the outer ring shall not exceed 3 degrees.

Product series
Miniature series: 10x, 12x, 13x
Universal series: 12xx, 13xx, 22xx, 23xx

To use
Self-aligning roller bearing: suitable for bearing heavy load and impact load, precision instruments, low noise motor, automobile, motorcycle, metallurgy, rolling mill, mine, oil, paper making, cement, sugar and other industries and general machinery.
