Self-aligning ball bearing
Self-aligning ball bearings with a cylindrical hole and tapered bore two structures, retainers made of steel sheet, synthetic resin and so on. Its characteristic is the outer spherical raceway and the mind is automatically adjusted, can compensate the error caused by the concentricity and deflection, but its inner, outer ring relative inclination of not more than 3 degrees.
Mini Series
10x、12x、13x
Universal series
12xx、13xx、22xx、23xx
Self-aligning ball bearing product characteristics
Mainly bear radial load, can withstand axial load. At the same time the smaller axis (shell) axial displacement limit in the clearance limits, with automatic self-aligning performance, allowing in normal peripheral small relative tilt conditions, suitable for bearing hole can not strictly ensure the concentricity of the components
Structural form of self-aligning ball bearing
With the dust cover and the sealing ring of the ball bearing assembly has been filled with the appropriate amount of grease, should not be installed before the heating should not be cleaned, the use of the process does not need to be lubricated to adapt to the operating temperature - 30 degrees Celsius to + 120 degrees Celsius
Application scope
Self-aligning ball bearings are designed to withstand heavy loads and impact loads, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, rolling mills, mines, oil, paper, cement, sugar and other industries and general machinery
