The self-aligning property of a self-aligning ball bearing is reflected in its ability to compensate for errors caused by misalignment and shaft deflection to a certain extent. Of course, this error has limits; the relative tilt between the inner and outer rings of a self-aligning ball bearing generally cannot exceed 3°. Like many other bearing products, self-aligning ball bearings also use a matching cage.
Self-aligning ball bearings come in two types: cylindrical bore and tapered bore. The cage can be made of steel sheet or synthetic resin. Common models of radial ball bearings that are available through HZK Bearing include 1200 series，1300 series，2200 series，2300 series and Micro series: 10x, 12x, 13x.
HZK self-aligning ball bearings are self-aligning ball bearings typically consisting of an inner ring, an outer ring, rolling elements (balls), and a cage. The inner surface of the outer ring is spherical, while the outer surface of the inner ring is flat. This design allows the bearing to self-adjust within a certain range to accommodate shaft eccentricity and misalignment.
The operating principle of self-aligning ball bearings is based on rolling friction. The rolling elements roll between the inner and outer rings, reducing frictional losses and improving operating efficiency. The spherical design of the outer ring allows the bearing to automatically adjust within a certain range, thereby reducing the impact of eccentric forces caused by improper installation or during equipment operation.
