The description of friction less self-aligning ball bearings 1207
1. The self-aligning ball bearings consist of two rows of balls and a common concave sphered raceway in the outer ring and the inner ring.
2. This type bearings have the self-aligning capacity which make the bearings insensitive to angular misalignments of the shaft relative to the housing.
3. The series of the bearings: 1200, 1300, 2200, 2300 and so on.
4. The bearings are also available with a cylindrical bore or, in certain size ranges, with a tapered bore
5. The bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected
6. The self-aligning ball bearings have the lowest friction at high speed.
Self-aligning ball bearings are suitable for applications where misalignment can arise from errors in mounting or shaft deflection. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Accordingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted.
Physical characteristics of self-aligning ball bearings
•The self-aligning ball bearing has two rows of balls.
•A common concave sphered raceway in the outer ring.
•The center of whose curvature meets that of the bearing it, so that the inner ring, balls and cage continue to rotate.
•The self-aligning ball bearing with a tapered bore can easily be fit to the shaft with an adapter assembly.
Advantages of self-aligning ball bearings
•Have the lowest friction of all rolling bearings.
•Run cooler even at high speeds.
•Easy mounting and dismounting.
•The permissible operating speed is not dependent on the common criteria like heat generation or cage stability and strength.
Applications of self-aligning ball bearings
•Self-aligning ball bearings are used for commercial ground shafting applications.
•Since axial load capacity is limited, self-aligning ball bearings are not suitable for applications with heavy axial loads.
•Furthermore, if an adapter is used on the tapered bore of the inner diameter, installation and disassembly are much simpler and for this reason adapters are often used on equipment with drive shafts.
