Decoding SKF 2305 M
- 23Series
- Self-aligning ball bearings, 23 series. Series differ in outside diameter and width even when the bore is the same.
- 05Bore
- Bore 25 mm (05 × 5).
- MSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2305 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2305 M measures 25 mm across the bore and 62 mm across the outside diameter; its width is 24 mm (25 x 62 x 24 mm).

For equipment where shafts may flex or alignment is not perfect, SKF M series self-aligning ball bearings provide a practical solution. These double-row bearings feature a spherical raceway that accommodates radial and axial loads in both directions while compensating for misalignment. MR Industrial Accessories supplies this series to maintenance and purchasing teams across the United States and Latin America.
The part number tells you the series and cage type. The numeric portion indicates size and series: 12-series (narrow) includes 1224 M and 1226 M; 22-series (medium) covers 2219 M, 2220 M, and 2222 M; 23-series (wide) comprises 2304 M, 2305 M, and 2306 M. The M suffix means a machined brass cage, which offers greater strength and higher temperature capability than a sheet metal cage.
These bearings suit driven equipment where alignment is challenging: industrial fans, centrifugal pumps, conveyors, textile machinery, agitators, and dryers. They are common in food, chemical, and petrochemical plants, as well as metalworking operations. The self-aligning action minimizes added stresses, which helps reduce wear and extend service life in setups with long shafts or separated supports.
Selection depends on the radial and axial loads, rotational speed, and operating environment. If dust or moisture is present, consider sealed or shielded variants. Lubrication must match the temperature and speed; high-quality grease is often used. During mounting, check initial alignment, use proper tools, and avoid impacts that could damage the brass cage.
When replacing a bearing, verify interchangeability carefully. Other brands may use similar designations, but dimensions and load ratings can differ. Always compare the complete code and specifications. MR Industrial Accessories can advise on equivalents and help you find a suitable replacement that maintains your equipment's performance.

Frequently asked questions
- SKF 2305 M bearing: what are its dimensions?
- SKF 2305 M measures 25 mm across the bore and 62 mm across the outside diameter; its width is 24 mm (25 x 62 x 24 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2305.
- What does the M suffix indicate on an SKF bearing?
- The M suffix denotes a machined brass cage, which is more robust and suitable for higher temperatures and speeds compared to steel sheet metal cages.
- When should I use a self-aligning ball bearing?
- Use one when the shaft may become misaligned relative to the housing due to deflection, mounting errors, or thermal expansion. The self-aligning capability prevents additional stresses and extends bearing life.
- How do I request a quote for SKF M series bearings?
- Send the complete bearing code via WhatsApp or email to MR Industrial Accessories. We will reply with a quote based on your requirement.
