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 limited mounting width, but loads and speeds are demanding. MR Accesorios Industriales carries this INA line in Buenos Aires, Argentina, and helps you identify the exact part number for your application.

The NA ZW XL series designation 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 to 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 radial shaft 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.

Regarding equivalents, 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 carries INA as an official brand and can advise you on interchangeability without inventing part numbers that do not exist in the catalogue.

If you already have the bearing part number you need, send it by WhatsApp to MR Accesorios Industriales and we will quote you shortly. If you are not sure of the designation, send us the shaft, housing and width measurements, and we will help you identify the NA ZW XL series or the corresponding alternative. We work with more than 80 years of experience in the industrial sector, since 1945, in Buenos Aires, Argentina.
