Decoding SKF 2306 M/P6
- 23Series
- Self-aligning ball bearings, 23 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- M/P6Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2306 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2306 M/P6 measures 30 mm across the bore and 72 mm across the outside diameter; its width is 27 mm (30 x 72 x 27 mm).

When shaft and housing alignment is not perfect, the SKF 2305 M/P6 self-aligning ball bearing compensates for angular misalignment thanks to its double-row design and spherical outer ring surface. It handles radial loads and moderate axial loads, making it a practical choice for transmissions, pumps and industrial fans.
Reading the part number helps you confirm what you are ordering. The first two digits, 23, identify the double-row self-aligning ball bearing series. The following number gives the bore diameter when multiplied by 5. The M suffix means the cage is machined brass, a construction that tolerates high speeds and elevated temperatures. The /P6 suffix shows precision class 6 per ISO, which holds tighter tolerances than the normal class. These details let you match the bearing to the application without guessing.
Typical installations include industrial fans, centrifugal pumps, compressors, conveyor belts and machine tools. Because the bearing can self-align, it suits equipment where shafts flex or housings are not perfectly machined. It also works in combined-load situations where the axial component stays moderate. Industries such as food processing, cement, steel, paper and petrochemical rely on this type of bearing for daily operations.
Selection depends on the radial and axial loads, rotation speed and operating environment. If dust or moisture is present, consider sealed or shielded versions. Lubrication matters: use high-quality grease for high temperatures or oil in circulating systems. During mounting, check initial alignment and avoid hitting the outer ring. The brass cage requires careful handling to prevent deformation.
Self-aligning ball bearings follow international standards, so a similar code from another manufacturer may be interchangeable. However, suffixes and tolerances can differ. Always verify exact dimensions and tolerances before substituting. The SKF 23 series with M suffix and P6 class has equivalents in other brands, but confirm with the manufacturer's tables. MR Industrial Accessories supplies SKF bearings and can advise on interchangeability.

Frequently asked questions
- SKF 2306 M/P6 bearing: what are its dimensions?
- SKF 2306 M/P6 measures 30 mm across the bore and 72 mm across the outside diameter; its width is 27 mm (30 x 72 x 27 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2306.
- What does the M suffix indicate on an SKF bearing?
- The M suffix means the cage is machined brass. This material handles high speeds and temperatures better than stamped steel cages and is common in precision bearings.
- What is precision class P6?
- P6 is an ISO precision tolerance that is tighter than the normal class. It is used where greater rotational accuracy is needed, such as machine tool spindles.
- Can this bearing be replaced with another brand?
- It may be interchangeable if dimensions and tolerances match, but suffixes vary between manufacturers. Always verify the full code and consult us before replacing.
