How to read SKF 2305 M/VQ335
- 23Series
- Self-aligning ball bearings, 23 series. For the same bore, each series has a different outside diameter and width.
- 05Bore
- 25 mm bore: 05 × 5.
- M/VQ335Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2305 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

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.

Frequently Asked Questions
- What are the dimensions of the SKF 2305 M/VQ335 bearing?
- The SKF 2305 M/VQ335 bearing has a 25 mm bore, a 62 mm outside diameter and a 24 mm width (25 x 62 x 24 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2305.
- What does the suffix /VQ335 mean in an SKF bearing?
- The suffix /VQ335 is an internal SKF specification that may refer to dimensional tolerances, internal clearance or special manufacturing characteristics. It is not a universal code; to know its exact meaning, consult the manufacturer's technical documentation or seek advice from a specialist.
- Can I replace an SKF self-aligning ball bearing with one from another brand?
- Yes, as long as the main dimensions (bore, outside diameter and width) and internal clearance match. However, suffixes indicating cage, tolerances or lubrication may vary between manufacturers. Always verify the specifications before interchanging.
- How do I know if I need a self-aligning ball bearing instead of a rigid one?
- If the shaft can deflect, the housing is not perfectly aligned or the application involves combined loads with angular misalignment, a self-aligning ball bearing is the appropriate option. Rigid bearings do not compensate for misalignment and may fail prematurely under those conditions.
