Sphercial Ball Bearing

SKF Bearing Company is the inventor of self-aligning ball bearings which has the relatively advanced technology. Specific models can be found: Basic design of SKF self-aligning ball bearings, SKF seal self-aligning ball bearings and SKF self-aligning ball bearings of extended inner ring.

Structure of Spherical ball bearings
It is divided into cylindrical bore tapered bore, the cage made of steel sheet or synthetic resins. This kind of bearing outer ring raceway is spherical shape, so the good performance of its self-aligning, can compensate concentricity and deflection errors, though inclination of inner and outer ring must not exceed 3 degree angle.

Genenally spherical ball bearings have two rows of symmetrical spherical rollerwhich is also called self-aligning ball bearings). It made of a large spherical channel outer ring, a double channel inner ring,two row steel ball and cage. When it rotates, steel ball, cage and inner ring can make a certain degree toward the outer ring(can automatically adjust axis), and bearings box for pocessing, the installation of improper occurred axis displacement. But genenally the largest axis tilt not size 3 degrees. Type code for self-aliging ball bearing is “1”

Self-aligning ball bearings is mainly bear radial load. In radial load at the same time, how can carry axial load. Don't usually used to withstand pure axial load, because if subject to pure axial load of only one column steel ball bearing. Double row Self-aligning ball bearings have several structure forms, such as a tapered bore type (K for 1:12); A tapered bore and adapter sleeve or withdrawal sleeves and extended?inner ring double row self-aligning ball bearing;A tightening screw in inner ring double row self-aligning ball bearings. These structural variations can install fixed bearings in the optical axis (uses in drive shaft). Tight set also can adjust bearing radial clearance. Self-aligning ball bearings and full ball, no single keep frame, with double-sides shield. The aperture of this king bearing is not bigger than 10mm, commonly used for aircraft components. Did not need to lubricate again.

Features:
Mainly bear radial load as well as smaller axial load.Axial displacement of axial has self-aligning properties within the limited clearance, allowing normal work in relatively small inclination, suitable for part of bearing seat hole without concentricity.
