Decoding SKF 2307 E-RS1TN9/C3
- 23Series
- Self-aligning ball bearings, 23 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- E-RS1TN9/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2307 E-RS1TN9/C3 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 31 mm (35 x 80 x 31 mm).

When shaft and housing alignment cannot be held tightly, a self-aligning ball bearing is often the practical answer. The SKF E-RS TN series carries two rows of balls running on a spherical outer ring raceway, so it absorbs angular misalignment while taking moderate radial and axial loads. Rubber contact seals on both sides and a polyamide cage let it work in dusty or damp surroundings. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams across the United States and in several Latin American countries.
Reading the code helps you order the right variant. The E tells you the outer ring has a lubrication groove, RS means rubber contact seals sit on both sides, and TN identifies a glass fiber reinforced polyamide cage that is light and resists corrosion. The /C3 suffix points to internal radial clearance above standard, which suits thermal expansion or tighter fits. Take 2307 E-RS1TN9/C3 as an example: 2307 covers the size and series type.
Typical duty includes equipment where alignment shifts during operation: centrifugal fans and pumps, conveyors, mixers, grain dryers, road machinery and food processing lines. In those settings the RS seal keeps particles and moisture away from the raceways. The bearing's ability to self-align also limits wear in assemblies with flexed shafts or supports that are not perfectly true.
Selection comes down to the radial and axial load, the running speed and the surrounding conditions. Contact seals handle humid or dusty areas well, though at very high speeds they can build heat, so a variant with less seal contact may be worth reviewing. Choose C3 clearance when the shaft or housing fit is interference or when temperature differences across the bearing are expected. At assembly, check alignment first and apply the grease specified for the application.
On equivalences: self-aligning ball bearings from other makers can often be swapped in when dimensions and clearance line up, but the E-RS TN series is not the same as versions with different seals or cages. Comparing the full code plus the operating conditions is the reliable route. MR can review the original designation and point you to a suitable match.

Frequently asked questions
- SKF 2307 E-RS1TN9/C3 bearing: what are its dimensions?
- SKF 2307 E-RS1TN9/C3 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 31 mm (35 x 80 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2307.
- What does the C3 suffix mean on a self-aligning bearing?
- It marks internal radial clearance larger than standard. It is chosen when the bearing runs hot or when the shaft or housing fit is tight, so the clearance does not close up and cause binding.
- Does this bearing come with rubber seals?
- Yes. RS means rubber contact seals on both sides, which block dust and moisture and hold the lubricant in. Keep in mind that contact seals have a speed limit, since they can overheat if pushed too far.
- Can I replace a self-aligning bearing from another brand with this SKF one?
- Often yes, provided dimensions and clearance agree. Not every self-aligning bearing is interchangeable, so check the complete code and the working conditions. Send us the original code and we will help you find the right equivalence.
