SKF double row angular contact bearings are components designed to withstand combined radial and axial loads in both directions. Their design with two rows of balls and inclined raceways allows them to handle tilting moments and high axial loads. They are used in applications requiring high precision and rigidity, such as machine tool spindles, pumps, gearboxes and transmission equipment. At MR Accesorios Industriales we sell this SKF line, a brand we sell, to provide reliable solutions to Argentine industry.
The designation of these bearings follows a standardized system. For example, in 3200 A-2RS1TN9/MT33, the prefix 3200 indicates the dimension series; the letter A indicates an internal variant; 2RS1 corresponds to rubber seals on both sides; TN9 identifies the polyamide cage; and MT33 specifies the type of grease. Other suffixes may indicate internal clearance or precision. Knowing these codes is key to selecting the correct bearing for the application.
These bearings are used in a wide variety of industries in Argentina. They are common in machine tool spindles, centrifugal pumps, compressors, speed reducers, power transmission equipment and textile machinery. Their ability to withstand axial loads in both directions makes them ideal for applications requiring high rigidity and precision, such as milling machine heads or industrial robot axes.
To select the right bearing, take into account the magnitude and direction of the loads, the rotational speed and the environmental conditions. The 2RS1 sealing protects against contaminants and retains lubrication, ideal for dirty or humid environments. The TN9 polyamide cage reduces weight and improves high-speed behavior. During mounting, ensure precise alignment and apply the recommended preload to avoid excessive clearance. Proper lubrication, such as MT33 grease, is essential for bearing service life.
There are cross-brand equivalents on the market for this type of bearing. When looking for a replacement, verify that the main dimensions, seal type and load capacity match the original specifications. Brands such as SKF, FAG, NSK or NTN offer equivalent products, but it is important to consult interchange tables to ensure compatibility.

Frequently Asked Questions
- What are the dimensions of the SKF 3306 A-2RS1TN9/MT33 bearing?
- The SKF 3306 A-2RS1TN9/MT33 bearing has a 30 mm bore, a 72 mm outside diameter and a 30.2 mm width (30 x 72 x 30.2 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3306.
- What does the 2RS1 suffix mean on an SKF bearing?
- The 2RS1 suffix indicates that the bearing has rubber seals on both sides. These seals protect against the entry of contaminants and retain lubrication, extending bearing service life in adverse environments.
- What is the difference between a single row and a double row bearing?
- A double row bearing has two rows of balls, which allows it to withstand axial loads in both directions and tilting moments. Single row bearings only withstand axial loads in one direction, so they require mounting in pairs.
- How do I choose the right angular contact bearing for my application?
- Consider radial and axial loads, speed, environmental conditions and available space. Check the seal type, cage and lubrication. Consult us with your equipment data and we will help you select the correct SKF bearing.
