Aligning ball bearing basic structure: double row self-aligning ball bearing cylindrical bore, there are tapered bore, conical taper bore 1: 12, 1: 30. Double row self-aligning ball bearings with a tapered bore by means of a locking nut can be fixed directly on the tapered journal, also choose the appropriate size adapter sleeve or withdrawal sleeve easily be mounted on a cylindrical shaft bearing. Using an adapter sleeve can also adjust the bearing radial clearance. Aligning ball bearing cages are mostly steel stamping cage use. Also available with glass fiber reinforced polypropylene nylon 6.6, machined solid brass cage-aligning ball bearings.

Aligning ball bearing axial load carrying capacity: When using an adapter sleeve aligning ball bearings, mounted on the optical axis without shaft shoulder, the axial load carrying capacity depends on the friction between the adapter sleeve and the shaft, which the maximum permissible axial load estimate using the following formula: Fp = 0.003Bd {where: Fp - the maximum permissible axial load, KN; B - bearing width, mm; D - bearing diameter, mm}
