Self-aligning ball bearings 2316

Self-aligning ball bearings, also known as self-aligning ball bearings, have two rows of ball bearings, the inner ring having two rolling faces and the outer ring having a spherical roller with the center of the sphere coincident with the bearing axis. . Thus, the axis of the inner ring and the cage can rotate around this center without causing any load stress. This allows bearings to work in conditions where there is a small angle of misalignment between the cylindrical faces of the inner and outer rings (machining errors, assembly errors). Therefore, they are called self-aligning bearings. This type of ball can usually have a taper hole for assembly using a sleeve (conical sleeve).

Double row ball bearings are double row steel ball bearings, the groove surface of the outer ring is a sphere matching the bearing center, the inner ring has double grooves. When rotating, the steel ball, cage and inner ring can tilt freely relative to the main axis of the outer ring to a certain extent, that is, it has the so-called self-aligning performance, so it can automatically adjust shaft and bearing housing. due to improper processing and installation And the error due to misalignment but the relative inclination of the inner and outer faces should not exceed 3.

The international designation of this type of bearing usually has 4 codes starting with number 1 or number 2.
