Self-aligning roller bearing

Description

Self-aligning ball bearing outer ring raceway was spherical, with self-aligning properties, it can automatically adjust the shaft or housing deflection or a different axis errors caused by heart. Self-aligning ball bearings mainly bear radial load, axial load while the smaller bear. Axis (shell) of the axial displacement limited clearance within the limits of performance with automatic self-aligning, allowing, the periphery is relatively little inclination to work under conditions suitable for bearing seat hole can not be strictly guaranteed concentricity of the components in the. Self-aligning ball bearing outer ring raceway is processed into spherical shape, there are two inner raceway of the double row deep groove ball bearings, with self-aligning properties. Its mainly used to bear radial load, radial load at the same time, it can withstand a small amount of axial load, but generally can not afford a pure axial load, its speed limit lower than the deep groove ball bearings. This class is used in load bearing more prone to bending under the action of the double bearing shaft, and the pairs of bearings Kong can not guarantee the strict concentricity of components inside, but the inner and outer ring of the centerline of the centerline of the relative inclination not more than 3 degrees.
