The SKF double row angular contact bearing is a ball bearing with two rows in parallel, designed to support radial and axial loads in both directions. Its compact construction allows replacing two single row bearings in a single housing, simplifying design and assembly. It is used in equipment requiring high load capacity in little space, such as pumps, gearboxes and machine tools. MR Accesorios Industriales sells this line with technical advice so you can choose the correct part number.
The designation of this series combines a four-digit basic number with suffixes indicating design features. For example, in 3204 A-2RS1, the prefix 32 corresponds to the medium-section double row series; the next two digits (04) indicate the bore size according to a code that does not translate directly to millimeters. The suffix A indicates an internal design variant, and 2RS1 indicates rubber sealing on both sides. Other examples such as 3306 A-2RS1 show series 33, of wider section. Knowing these codes allows you to quickly identify the bearing's characteristics.
In Argentine industry, these bearings appear in centrifugal pumps, speed reducers, compressors, industrial fans and machine tools. Their ability to support combined loads makes them suitable for shafts where radial and axial forces occur simultaneously. They are also found in power transmission equipment, such as gearboxes and conveyor systems. Being double row, they offer greater rigidity than a single row bearing, which contributes to more stable and quieter operation in demanding applications.
To select the right bearing, take into account the radial and axial load it must support, the rotational speed and the environmental conditions. The 2RS1 seal protects against dust and moisture, but if the equipment operates at high temperatures or speeds, an open design or one with metal shields may be preferable. During assembly, check shaft and housing alignment, and apply the lubrication recommended by the manufacturer. Incorrect fitting can cause noise, vibration and premature wear. If in doubt, consult us with your application data.
SKF bearings are interchangeable with products from other brands that follow the same standardized dimensions. When looking for a replacement, compare the complete part number, including suffixes, because a sealing or internal clearance variant can change performance. Not all bearings with the same basic number are identical: additional letters indicate design differences. If you need an equivalence, send us the original part number and we will help you find the right option within our bearing line.

Frequently Asked Questions
- What are the dimensions of the SKF 3212 A-2RS1 bearing?
- The SKF 3212 A-2RS1 bearing has a 60 mm bore, a 110 mm outside diameter and a 36.5 mm width (60 x 110 x 36.5 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3212.
- 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 dust, water and other contaminants, and retain lubrication. They are suitable for environments with moderate dirt, but can increase friction and limit maximum speed compared to open designs.
- How do I identify whether a double row bearing replaces two single row ones?
- It is not a direct equivalence. A double row bearing occupies a single housing and supports loads in both directions, while two single row bearings may require a specific arrangement. To evaluate a replacement, check the dimensions and load capacities. Send us your equipment data and we will advise you.
- Can I use these bearings at high speeds?
- The permissible speed depends on the design, lubrication and load. Bearings with 2RS1 seals usually have a lower limit than open ones due to seal friction. If your application requires high revolutions, it is essential to review the operating conditions and choose the appropriate variant. Consult us with your equipment parameters.
