Self-Aligning Ball Bearings. This type of bearing is recommended when alignment of the shaft and housing is difficult as the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing.Self-Aligning Double Row Ball Bearings. Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection.
Sealing is always an important consideration in recirculating linear bearings, but it becomes even more critical with self-aligning linear bushings. When a bushing tilts, a standard seal will lose contact with the shaft and become ineffective. To prevent this, self-aligning bushings are generally offered with floating seals, which maintain consistent contact with the shaft to ensure protection.Bearings Direct is a ball bearings supplier with over twenty years of experience in the industry. Ball bearings consist of a series of round balls in a casing, within an inner and outer ring capable of supporting both radial and axial (thrust) loads.
