SKF self-aligning ball bearings of the 23 series are double-row ball bearings with a spherical raceway in the outer ring, which allows them to self-align and compensate for angular misalignment between shaft and housing. They are used in applications where shaft deflection or mounting errors are unavoidable, such as fans, belt drives and continuous process equipment.

The designation of these bearings combines the series number with suffixes that indicate design particularities. In the examples 2305 M/VQ335 and 2309 M/VQ335, the prefix 23 corresponds to the medium-section self-aligning ball bearing series, with standardized bore diameter and outside diameter. The letter M indicates a machined brass cage, suitable for higher demands. The suffix /VQ335 identifies an internal manufacturer specification, generally linked to special tolerances or clearance. To correctly interpret each case, it is essential to consult the complete designation.

These bearings are used in equipment where perfect alignment is not guaranteed: industrial fans, blowers, belt drives, conveyors, textile machines, centrifugal pumps and mixers. In Argentina, they are common in the food, chemical and cement industries and in water treatment plants. Their self-aligning capability reduces premature wear and extends the service life of the assembly, even when the shaft deflects under load or the housing is not perfectly machined.

To select correctly, take into account the radial and axial load to be supported, the rotation speed and the environmental conditions. Sealing is key: if there is dust or moisture, choose variants with additional seals or shields. Lubrication must be suitable for the working temperature; in many cases, lifetime grease is sufficient, but in critical applications relubrication may be required. During mounting, verify the initial alignment and avoid striking the rings; use suitable mounting tools to avoid damaging the raceways.

Regarding equivalences, SKF series 23 self-aligning ball bearings can be interchanged with products from other brands that follow the same dimensional and clearance designation. However, not all suffixes are equivalent between manufacturers; for example, a brass cage may be identified differently. Always verify tolerances and axial and radial clearance before replacing one bearing with another of a different brand. If you have doubts, consult us with the original code and we will advise you.
