The SKF needle roller bearing of the PNA series is a compact radial bearing, with outer and inner rings and a needle cage. It is used when radial space is limited and radial loads must be supported with high rigidity. It is common in applications where a reduced-section bearing is needed, such as machine tools, transmission equipment and precision mechanisms. MR Accesorios Industriales carries this series as part of its SKF bearing line.

The PNA series designation reads with the prefix PNA followed by two numbers separated by a slash: the first indicates the bore diameter and the second the outer diameter. For example, PNA 12/28 has a 12 mm bore and 28 mm outer diameter; PNA 20/42, a 20 mm bore and 42 mm outer diameter. The suffix may include cage or seal variants, but in this series the listed examples do not carry additional suffixes. To correctly interpret each part number, it is best to follow the published examples.

This type of bearing is used in industries such as metalworking, food, textile and automotive. In Argentina, it is common to find it in machine tool spindles, pumps, compressors and belt or chain transmission systems. It is also used in linear motion equipment and in applications where a bearing with a low radial section is required. Its ability to support high radial loads with little space makes it suitable for compact mechanisms.

To select a PNA bearing, take into account the bore and outer diameters, which define the load capacity and permissible speed. Verify that the housing and shaft have the appropriate tolerance and that lubrication is correct for the application. During assembly, ensure precise alignment to avoid unforeseen axial loads. If the bearing does not have an integrated seal, consider protecting it against external contaminants. The needle cage allows high speeds, but requires adequate lubrication.

As for equivalents, needle roller bearings with the PNA designation can be found from other brands under similar nomenclatures, although they are not always directly interchangeable. Factors such as tolerance, internal clearance and cage type may vary between manufacturers. Therefore, when replacing a bearing, it is advisable to verify the critical dimensions and operating conditions. MR Accesorios Industriales can advise you on compatibility with other brands, but it is always necessary to confirm with the technical specifications.
