The SKF cylindrical roller bearing of the NJ series with TN/VA suffix is a radial bearing with high load capacity that you can use in equipment with severe demands. Its design with polymer cage and special treatment makes it suitable for applications where strength and reliability are required. MR Accesorios Industriales sells this line as an official brand and helps you identify the correct designation for your equipment.

The designation of the NJ TN/VA series reads as follows: NJ indicates that it is a single-row cylindrical roller bearing with a rib on the inner ring, which allows it to support axial loads in one direction. The suffix TN indicates an injected polymer cage, and VA refers to a special execution, usually with heat treatment or coating for particular conditions. A concrete example is NJ 130X240 TN/VA820, where the numbers define dimensions and the final code the exact variant. Send me that code and we will verify it together.

This type of bearing is used in industries in Argentina such as cement, steel, mining, oilseed and pulp and paper. It is present in gearboxes, centrifugal pumps, industrial fans, mills, conveyor belts and continuous process equipment. Its ability to support high radial loads and moderate speeds makes it a frequent option in fixed power transmission. If your equipment operates with shocks or vibrations, this series offers good performance.

To select the correct bearing, take into account the radial and axial load it must support, the rotation speed and the type of lubrication. Sealing is key: if the environment has dust or humidity, an execution with seals or shields is advisable. The internal clearance must be adequate for the working temperature. During assembly, verify the alignment of the supports and use the correct tools to avoid damaging the rollers or the cage. Clean and well-dosed lubrication extends service life.

Regarding equivalences, cylindrical roller bearings from different brands can be interchanged if main dimensions, tolerances and clearance match. The NJ series with TN/VA suffixes has equivalents in other manufacturers, but the exact designation varies. Do not invent codes: send us the one on your equipment or drawing and we will cross-reference it with the SKF line we sell. This way you avoid assembly errors and buy what your machine really needs.
