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 ideal for industrial equipment operating at moderate and high speeds, such as pumps, compressors and gearboxes. At MR Accesorios Industriales we supply them as part of our SKF bearing line.
The designation of these bearings follows a system that combines numbers and suffixes. For example, in 3308 ANR/C3, the first digits indicate the size and series. The suffix ANR indicates a variant with specific sealing or internal clearance characteristics, while C3 indicates a radial clearance greater than standard. It is essential to interpret these codes correctly to ensure compatibility with your equipment. If you have doubts, our technical team can help you identify the right bearing.
These bearings are used in a wide variety of industrial applications in Argentina. They are commonly found in centrifugal pumps, screw compressors, gearboxes and machine tools. Their ability to support combined loads makes them suitable for equipment requiring high precision and rigidity, such as milling machine spindles or transmission shafts. They are also used in the food and chemical industries, where reliability is critical.
To select the correct bearing, it is essential to consider radial and axial loads, operating speed and environmental conditions. Mounting must be carried out with suitable tools to avoid damage to the raceways. Lubrication must be appropriate for the type of seal and working temperature. Alignment between shaft and housing is crucial to maximize service life. At MR Accesorios Industriales we have the experience to advise you at every step.
Regarding equivalences, SKF double row angular contact bearings can be interchanged with those of other brands that follow the same dimensional designation. However, it is important to verify tolerances and internal clearance, as they may vary between manufacturers. We always recommend consulting our technical team before replacing one bearing with another of a different brand to ensure optimal operation.

Frequently Asked Questions
- What are the dimensions of the SKF 3311 ANR/C3 bearing?
- The SKF 3311 ANR/C3 bearing has a 55 mm bore, a 120 mm outside diameter and a 49.2 mm width (55 x 120 x 49.2 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3311.
- What does the C3 suffix mean in these bearings?
- The C3 suffix indicates an internal radial clearance greater than standard. This is useful in applications where there are temperature differences between shaft and housing, or where mounting interference needs to be compensated.
- Are these bearings suitable for high speeds?
- Yes, SKF double row angular contact bearings are designed to operate at moderate and high speeds, depending on lubrication and mounting. Consult the technical specifications for each application.
- Can I replace a bearing from another brand with an SKF one?
- In general, yes, as long as dimensions and tolerances are equivalent. However, it is advisable to verify internal clearance and operating conditions. Our team can help you validate interchangeability.
