How to read SKF 2307 EM/C3
- 23Series
- Self-aligning ball bearings, 23 series. For the same bore, each series has a different outside diameter and width.
- 07Bore
- 35 mm bore: 07 × 5.
- EM/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2307 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 2307 EM/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 31 mm width (35 x 80 x 31 mm).

SKF self-aligning ball bearings of the 23 series are double-row ball bearings with a spherical raceway in the outer ring, allowing them to compensate for angular misalignment between shaft and housing. They are used in equipment where perfect alignment cannot be guaranteed, such as fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales supplies this line as part of its SKF bearing range.
The designation of these bearings follows the SKF system: the basic number, for example 2307, indicates the type and dimension series. In this case, the prefix 23 corresponds to a series of self-aligning ball bearings with standard dimensions. Suffixes provide additional information: EM indicates that the bearing has a machined brass cage, suitable for higher speeds and temperatures; C3 indicates an internal radial clearance greater than normal, recommended when there are tight fits or thermal differences between shaft and housing. Thus, a 2307 EM/C3 combines these characteristics.
These bearings are used in industries such as food, chemical, cement and aggregate processing. They are found in industrial fans, centrifugal pumps, belt conveyors, mixers, screens and transmission equipment. Their self-aligning capability makes them useful in assemblies where the shaft may flex or where the housing is not perfectly rigid. They are also found in agricultural machinery and tillage implements, where dust and variable load demand robustness.
For correct selection, consider radial and axial load, rotational speed and environmental conditions. The EM suffix with brass cage is suitable for demanding regimes; if the environment is very dirty, consider additional seals. The C3 clearance is useful when the shaft fit is tight or there are thermal gradients. During mounting, ensure reasonable initial alignment and adequate lubrication: grease or oil as appropriate. Permissible misalignment is limited; it does not replace careful alignment.
When looking for equivalents, remember that each manufacturer has its own nomenclature. A self-aligning bearing from another brand with similar dimensions and clearance may be interchangeable, but always verify tolerances and cage type. Not all suffixes match between brands. If you need to replace an existing bearing, the safest approach is to compare the main dimensions (bore, outer diameter and width) and operating conditions. MR Accesorios Industriales can advise you on the right equivalent.
If you have the code of your SKF self-aligning bearing, send it via WhatsApp to MR Accesorios Industriales and we will quote you. We can also help you identify the replacement if you provide measurements or a photo. MR Accesorios Industriales is your partner for bearings and power transmission.

Frequently Asked Questions
- What are the dimensions of the SKF 2307 EM/C3 bearing?
- The SKF 2307 EM/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 31 mm width (35 x 80 x 31 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2307.
- What does the EM suffix mean on an SKF bearing?
- The EM suffix indicates that the bearing has a one-piece machined brass cage, guided by the rolling elements. This cage is more resistant and suitable for high speeds and temperatures than standard sheet metal cages.
- What is the C3 clearance for?
- The C3 radial clearance is greater than normal. It is used when the fit on the shaft or housing is tight, or when there are thermal differences between parts, to prevent the bearing from becoming preloaded and failing prematurely.
- How do I know if a bearing from another brand is equivalent?
- Compare the main dimensions (bore, outer diameter and width) and the load and speed conditions. Suffixes may vary between manufacturers, so also verify the cage type and radial clearance. If in doubt, consult us with the original code.
