The INA needle roller bearing of the NA ZW XL series is a radial bearing with high load capacity in a very small space. It is used when the design requires a small outside diameter and a limited mounting width, but loads and speeds are demanding. MR Accesorios Industriales sells this INA line in Buenos Aires, Argentina, and helps you identify the exact part number for your application.

The designation of the NA ZW XL series is read in blocks. NA indicates that it is a needle roller bearing with machined inner and outer rings, suitable for high radial loads. ZW indicates the design with two rows of needles, which doubles the load capacity compared with a single row. XL identifies the current generation of the product within the INA catalogue. The numbers that follow the base code, as in NA69/32-ZW-XL or NA6910-ZW-XL, define the size: in the 69 series, the numeric suffix relates to the bore diameter and the standardized outside diameter.

These bearings are chosen in industries where radial space is critical: machine tools, transmission equipment, pumps, compressors, cranes and lifting systems. In Argentina they are seen in industrial plant maintenance, road equipment, mills and conveyors. Their ability to withstand high radial loads with a low profile makes them common in gearboxes and joints where a conventional ball or roller bearing does not fit.

To select the correct part number, take into account the shaft diameter, the available outside diameter and the mounting width. The NA ZW XL series does not include its own sealing in its base designation, so sealing must be handled in the housing or with external oil seals. Proper lubrication and precise alignment between shaft and housing are key to reaching the expected service life. If the mounting requires controlled internal clearance, ask about the specific variant.

As for equivalences, INA needle roller bearings can be interchanged with equivalent lines from other European or Asian brands, as long as the main dimensions, cage type and load capacity match. It is not enough for the part number to be similar: tolerances and clearance must be verified. MR Accesorios Industriales sells INA and can guide you on interchangeability.
