pressa for bearings used Self-Aligning Ball Bearings instruction:

Aligning ball bearing is a spherical outer ring raceway of the double row bearings. Inner ring, ball bearing cage can rotate freely around the center, with a tone Mind. The self-aligning capability can Errors of the shaft bearing deformation and deformation compensation. Aligning ball bearings for the upper shell of the center axis and the difficulties prone to deflection of the drive shaft bearings and other purposes.

Self-aligning ball bearing outer ring raceway is processed into spherical shape, the inner raceway with two double row deep groove ball bearings, aligning performance. It is mainly used to bear radial load, radial load at the same time, it can withstand a small amount of axial load, but generally can not bear the pure axial load, the speed limit lower than the deep groove ball bearings. This kind of bearings are used for the load prone to bending under the double bearing shaft, and dual bearings coaxial holes can not guarantee that the parts in the strict, but the inner ring and outer ring center line of the relative steepness of the center line of not more than 3 degrees.

 12,13,22 and 23 series of self-aligning ball bearing bore can be cylindrical or conical. Bearing bore taper 1:12 (code suffix K),-aligning ball bearings can be installed directly to the cone axis can also be installed by a tight sets to cylindrical shaft,  addition to providing non-aligning sealed ball bearings, can provide two

End with a sealing cover the basic types of self-aligning ball bearings (code suffix 2RS).

pressa for bearings used Self-Aligning Ball Bearing clearance

Basic types of cylindrical holes aligning ball bearings manufacturing group for the general group clearance, radial clearance larger than normal group bearing (code suffix C3) available on request. Basic types of tapered hole aligning ball bearing radial clearance larger than the normal group of C3 group.

Sealed self-aligning ball bearings

Sealed self-aligning ball bearings (code suffix .2 RS) at both ends with sealing covers (contact seal.) To ensure the life, they had joined the factory in the grease. Sealed bearings is limited to the minimum working temperature -30 °C.

Aligning ball bearings on the

Aligning ball bearings allow the shaft around the bearing center deflection of 4 °, sealed self-aligning ball bearings can compensate for the maximum 1.5 °.
