SKF double row angular contact bearings are components designed to support radial and axial loads in both directions. Their two-row ball construction allows superior performance in applications requiring high rigidity and precision. They are a reliable solution for industrial machinery operating under demanding conditions.
The designation of these bearings follows a clear system. For example, in 3205 A-2RS1/C3, the prefix 32 indicates the double row series, followed by the size code. The suffix A indicates an optimized internal design. 2RS1 means the bearing has rubber seals on both sides, which protects against contamination and retains lubricant. C3 indicates an internal radial clearance greater than standard, suitable for applications with high temperatures or interference fits. This nomenclature allows you to quickly identify the key features.
These bearings are used in a wide variety of industries in Argentina. They are common in centrifugal pumps, compressors, industrial fans, machine tools and power transmission equipment. Their ability to support combined loads makes them ideal for applications where the load direction changes or where rigid support is required. They are also found in mining equipment, cement plants and water treatment plants, where reliability is critical.
To select the right bearing, consider the magnitude and direction of the loads, the operating speed and the environmental conditions. The 2RS1 seal is effective against dust and moisture, but if higher speed is required, an open design may be preferable. C3 clearance is recommended when there are thermal gradients or tight fits. During assembly, ensure precise alignment and adequate lubrication. A clean environment and the use of appropriate tools prevent premature damage.
Regarding equivalences, SKF double row angular contact bearings can be interchanged with those of other brands that follow the same dimensional designation. However, differences in tolerances, internal clearance and sealing can affect performance. Always verify the technical specifications before replacing a bearing. MR Accesorios Industriales sells top-brand bearings and can advise you on the best option for your specific application.

Frequently Asked Questions
- What are the dimensions of the SKF 3307 A-2RS1/C3 bearing?
- The SKF 3307 A-2RS1/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 34.9 mm width (35 x 80 x 34.9 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3307.
- What does the 2RS1 suffix mean on these bearings?
- The 2RS1 suffix indicates that the bearing has rubber seals on both sides. These seals protect against the entry of contaminants and retain lubricant, extending the bearing's service life in dirty or humid environments.
- When is it advisable to use a bearing with C3 clearance?
- C3 clearance is suitable when the bearing operates at elevated temperatures or when mounted with interference fits that reduce internal clearance. It is also recommended in applications where thermal expansion must be compensated.
- Can I replace an SKF bearing with one from another brand?
- Yes, as long as the dimensions and tolerances are equivalent. However, verify the load, speed and sealing specifications, as they can vary between manufacturers. Contact us to ensure compatibility.
