SKF double row rigid bearings are ball bearings with two rows, designed to support radial and axial loads in both directions. Their compact construction and high rigidity make them ideal for applications requiring precision and load capacity in reduced spaces. At MR Accesorios Industriales we distribute this SKF line, an official brand we represent, with more than 80 years of experience in the industry.

The designation of these bearings follows the SKF system: the basic number indicates the size, and the suffixes provide key information. For example, in 3205 A-2Z, the prefix 32 corresponds to the double row series, the 05 to the bore diameter (multiplied by 5), the letter A indicates an internal variant and the suffix 2Z indicates that they have two protective metal shields, one on each side. Other suffixes such as 2RS would indicate rubber seals. Knowing these codes facilitates identification and ordering.

These bearings are used in a wide variety of industrial equipment: electric motors, pumps, compressors, fans, machine tools and conveyors. In Argentina, they are common in the food, chemical, petrochemical and manufacturing industries in general. Their ability to support loads in both directions makes them suitable for applications with moderate axial forces, such as gearboxes and spindles. MR Accesorios Industriales distributes them for replacement and new projects.

To select correctly, consider the radial and axial load, the rotation speed and the environmental conditions. Sealing is critical: models with the 2Z suffix offer protection against dust and particles, while 2RS provide better sealing against moisture and liquid contaminants. Proper lubrication and precise alignment during assembly extend service life. Avoid impacts and verify the internal clearance according to the application. If in doubt, consult the SKF tables or contact us.

Regarding equivalences, double row bearings from other brands may have similar designations, but they are not always directly interchangeable. Factors such as internal clearance, preload and cage type may vary. Always verify the critical dimensions and operating conditions before replacing one bearing with another from a different manufacturer. If you need advice, our technical team can help you find the best option.
