SKF E-2RS1TN9/C3 self-aligning ball bearings are double-sealed ball bearings with increased internal clearance. They are used in applications where there is misalignment between shaft and housing, since their spherical outer ring allows up to 4° of tilt. They are ideal for equipment with flexed shafts or difficult mounting. MR Accesorios Industriales sells them.
The designation of these bearings reads as follows: the base number (2204, 2205, etc.) indicates the size and dimension series. The suffix E indicates an optimized internal design. 2RS1 means double nitrile rubber seal on both sides, which retains lubricant and blocks contaminants. TN9 indicates a glass fiber reinforced polyamide cage, lightweight and resistant. /C3 is the increased internal radial clearance, suitable for high temperatures or interference fits. For example, 2205 E-2RS1TN9/C3 combines all these features.
In Argentine industry, these bearings are found in industrial fans, conveyors, textile machines, packaging equipment and mixers. Also in agricultural applications such as seeders and harvesters, where dust and weather demand effective sealing. Their self-aligning capability makes them useful on long shafts that flex under load, and in mountings where perfect alignment between supports cannot be achieved.
To select correctly, take into account radial and axial load, rotation speed and environmental conditions. The 2RS1 seal is suitable for environments with dust and moderate humidity, but not for immersion. C3 clearance is recommended when the bearing operates at temperatures above 70 °C or when the shaft fit is interference. During mounting, avoid striking the outer ring and verify the alignment of the supports. Lubrication comes from the factory; no additional maintenance is required.
Regarding equivalences, sealed self-aligning bearings with polyamide cage and C3 clearance from other brands can be interchanged if dimensions and tolerances match. Always verify the complete part number, since small variations in sealing or clearance change performance. MR Accesorios Industriales sells SKF, and we can advise you on interchangeability with other brands we also distribute.

Frequently Asked Questions
- What are the dimensions of the SKF 2205 E-2RS1TN9/C3 bearing?
- The SKF 2205 E-2RS1TN9/C3 bearing has a 25 mm bore, a 52 mm outside diameter and a 18 mm width (25 x 52 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2205.
- What does the suffix 2RS1 mean on these bearings?
- 2RS1 indicates double nitrile rubber seal on both sides. This seal retains lubricant and prevents the entry of dust and moisture, extending service life in contaminated environments. It is important not to confuse it with other seal types, such as 2RSH or 2RS2, which may have different performance.
- When is it advisable to use a bearing with C3 clearance?
- C3 clearance is suitable when the bearing operates at high temperatures, since thermal expansion reduces internal clearance. It is also recommended when the shaft fit is interference, because mounting compresses the inner ring. In normal applications, a standard CN clearance may be sufficient.
- Are they interchangeable with bearings from other brands?
- Yes, as long as the main dimensions and tolerances match. Sealed self-aligning bearings with polyamide cage and C3 clearance from different brands are usually interchangeable. However, verify the complete part number and consult us if you have doubts, because small differences in sealing or clearance can affect performance.
