The SKF double row angular contact bearing is a ball bearing with two rows working at an angle, designed to withstand combined radial and axial loads in both directions. It is used in applications requiring high precision and rigidity, such as machine tool spindles, pumps, compressors and gearboxes. MR Accesorios Industriales sells this SKF line.
The designation of this series is interpreted as follows: the basic number indicates the size, and the suffixes provide key information. For example, in 3203 A-2RS1TN9, the A indicates an internal design variant, 2RS1 indicates rubber seals on both sides, TN9 identifies a glass fiber reinforced polyamide cage and the base number defines the main dimensions. Knowing these codes allows you to order the exact bearing you need.
These bearings are used in industries such as metalworking, food, chemical and petrochemical. In Argentina, you will find them in milling machine and lathe spindles, centrifugal pumps, screw compressors, gearboxes and transmission equipment. Their double row and angular contact make them ideal for withstanding axial loads in both directions and simultaneous radial loads, with good rigidity and rotation precision.
To select the right bearing, take into account the combined load, the rotation speed and the environmental conditions. If the equipment operates with dust or moisture, choose the variant with 2RS1 seals. Proper lubrication and precise alignment of the shaft and housing are essential to avoid premature failures. Mounting must be done with suitable tools, without striking the rings, and verifying the internal clearance according to the application.
As for equivalents, double row angular contact bearings from different brands can be interchanged if dimensions and suffixes match. However, always verify the tolerances and axial clearance, as they may vary between manufacturers. SKF is a world reference brand and MR Accesorios Industriales sells it as part of its bearing line, with technical advice so that you choose the right option.
If you already have the part number of the bearing you need, send it by WhatsApp to MR Accesorios Industriales and we will quote you promptly.

Frequently Asked Questions
- What are the dimensions of the SKF 3203 A-2RS1TN9 bearing?
- The SKF 3203 A-2RS1TN9 bearing has a 17 mm bore, a 40 mm outside diameter and a 17.5 mm width (17 x 40 x 17.5 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3203.
- What does the 2RS1 suffix mean in an SKF bearing?
- The 2RS1 suffix indicates that the bearing has rubber seals on both sides. These seals protect against the entry of dust, water and contaminants, and retain the lubricant. They are ideal for applications in dirty or humid environments.
- Does this bearing withstand axial loads in both directions?
- Yes, the double row angular contact design allows it to withstand axial loads in both directions, in addition to radial loads. This makes it suitable for applications with combined loads and rigidity requirements.
- How do I request a quote for this bearing from MR?
- Send the full bearing part number by WhatsApp to MR Accesorios Industriales. If you do not have it, send us the shaft and housing dimensions or a photo, and we will help you identify it. We will quote you promptly.
