How to read SKF 3212 A-2RS1/MT33
- 32Series
- Double row angular contact ball bearings, 32 series. For the same bore, each series has a different outside diameter and width.
- 12Bore
- 60 mm bore: 12 × 5.
- A-2RS1/MT33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
3212 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF double row angular contact ball bearings are components designed to support combined radial and axial loads in both directions. Their design with two rows of balls and inclined raceways allows them to handle significant axial forces with high rigidity. They are used in applications requiring precision and load capacity, such as machine tools, pumps and gearboxes. At MR Accesorios Industriales we supply this SKF line, a brand that MR carries, for the Argentine market.
The designation of these bearings follows a scheme combining numbers and suffixes. For example, in 3204 A-2RS1/MT33, the first digits indicate the series and size; the letter A indicates an internal design variant; 2RS1 indicates double rubber seal; and MT33 refers to the grease type and internal clearance. Other examples such as 3206 A-2RS1/MT33 or 3309 A-2RS1/MT33 share the same structure, varying only in size. Knowing these suffixes is key to choosing the correct bearing for the application.
These bearings are used in industries such as metallurgy, cement, paper and food. In Argentina, they are common in centrifugal pumps, industrial fans, conveyor belts and machine tools. Their ability to support axial loads in both directions makes them ideal for shafts requiring high rigidity and precision. They are also used in gearboxes and spindles, where rotation accuracy is essential to the production process.
To select the right bearing, take into account the radial and axial load it must support, as well as the rotation speed and environmental conditions. The 2RS1 seal protects against contaminants and retains lubrication, but verify the operating temperature. The MT33 internal clearance is standard for many applications; if you need greater precision, ask about other variants. During mounting, ensure correct alignment and avoid impacts that could damage the raceways. Proper lubrication extends service life.
Regarding cross-references, SKF double row angular contact ball bearings can be interchanged with those from other brands that follow the same dimensional designation. However, not all suffixes match; for example, sealing or clearance may vary between manufacturers. Always verify the technical specifications before replacing a bearing. At MR Accesorios Industriales we can advise you on interchangeability and source the part you need.

Frequently Asked Questions
- What are the dimensions of the SKF 3212 A-2RS1/MT33 bearing?
- The SKF 3212 A-2RS1/MT33 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 double rubber seals on both sides. This provides an effective barrier against the entry of contaminants such as dust and moisture, and helps retain the lubricating grease, extending bearing service life in demanding environments.
- What is the difference between the 32 series and the 33 series?
- The 32 series and the 33 series differ in their dimensions and load capacity. Generally, the 33 series has a greater width and therefore higher axial and radial load capacity. The choice depends on the available space and the load requirements of the application.
- Can I replace an SKF bearing with one from another brand?
- Yes, it is possible to replace it with one of equivalent dimensions, but verify that the sealing, internal clearance and lubrication suffixes are compatible with your application. Not all manufacturers use the same nomenclature, so it is advisable to consult a specialist before making the change.
