How to read SKF 2307 E-RS1TN9/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.
- E-RS1TN9/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 E-RS TN series self-aligning ball bearing is a self-aligning bearing with two rows of balls and a spherical outer ring raceway. It is designed to support moderate radial and axial loads, and to compensate for angular misalignment between shaft and housing. Its RS seal and TN polyamide cage make it suitable for dusty or humid environments. It is used in fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales supplies it as a brand.
The E-RS TN series designation reads as follows: the E indicates that the outer ring has a lubrication groove; RS indicates that the bearing comes with rubber contact seals on both sides; TN corresponds to the glass fiber reinforced polyamide cage, lightweight and corrosion resistant. The /C3 suffix indicates a larger than standard internal radial clearance, useful when there is thermal expansion or tight fits. A specific example is 2307 E-RS1TN9/C3, where 2307 identifies the size and series type.
In Argentine industry, these bearings are found in equipment where perfect alignment is not guaranteed: grain dryers, conveyor belts, mixers, centrifugal fans and centrifugal pumps. They also appear in road machinery and in the food sector, where the RS seal prevents the ingress of particles. Their self-aligning capability reduces wear and extends service life in assemblies with flexed shafts or misaligned supports.
To select correctly, take into account the radial and axial load to be supported, the rotation speed and the environment. The RS seal is suitable for humid or dusty environments, but if the speed is very high it can generate heat; in that case, evaluate variants with less contact. The C3 clearance is recommended when the fit on the shaft or in the housing is interference or when there are thermal gradients. During assembly, verify the initial alignment and lubricate with the grease recommended by the manufacturer.
Regarding equivalences, self-aligning ball bearings from other brands with similar designations can be interchanged, but always verify dimensions and clearance. The SKF E-RS TN series is not identical to other series with different seals or cages. If you need to replace a bearing, the safest approach is to compare the complete code and the operating conditions. MR Accesorios Industriales can advise you on the correct equivalence.

Frequently Asked Questions
- What are the dimensions of the SKF 2307 E-RS1TN9/C3 bearing?
- The SKF 2307 E-RS1TN9/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 C3 suffix mean on a self-aligning bearing?
- The C3 suffix indicates a larger than standard internal radial clearance. It is used when the bearing operates at high temperatures or when the fit on the shaft or housing is very tight, to prevent the clearance from becoming too small and the bearing from seizing.
- Does this bearing come with rubber seals?
- Yes, the RS designation indicates that it has rubber contact seals on both sides. This protects against dust, humidity and lubricant loss. It is important not to exceed the maximum recommended speed for contact seals, as they can overheat.
- Can I replace a self-aligning bearing from another brand with this SKF one?
- In general yes, if dimensions and clearance match. But verify the complete code and the working conditions. Not all self-aligning bearings are interchangeable. Consult us with the original code and we will help you find the appropriate equivalence.
