The INA NA ZW XL series is a needle roller bearing built for radial loads where the mounting envelope is tight. Its machined inner and outer rings and two rows of needles let it carry heavy radial loads while keeping a small outside diameter and narrow width. MR Industrial Accessories supplies this INA line to maintenance and purchasing teams across the United States and Latin America, and helps confirm the exact part number for your application.

Reading the designation helps you verify a replacement. NA means a needle roller bearing with machined inner and outer rings, intended for high radial loads. ZW identifies a two-row needle design. XL marks the current generation of the product. The numbers after the base code set the size: in the 69 series, examples such as NA69/32-ZW-XL and NA6910-ZW-XL use the numeric suffix to define bore diameter and standardized outside diameter.

These bearings are selected where radial space is critical: machine tools, transmission equipment, pumps, compressors, cranes and lifting systems. In plant maintenance, road equipment, mills and conveyors, their low profile and radial capacity make them a common choice in gearboxes and joints where a conventional ball or roller bearing will not fit.

To select the right part number, confirm the shaft diameter, the available outside diameter and the mounting width. The base NA ZW XL designation does not include integral sealing, so sealing must be provided by the housing or external oil seals. Correct lubrication and precise alignment between shaft and housing are key to reaching the expected service life. If controlled internal clearance is required, ask about the specific variant.

INA needle roller bearings can be interchanged with equivalent lines from other European or Asian brands when the main dimensions, cage type and load capacity match. A similar part number is not enough: tolerances and clearance must be verified. MR Industrial Accessories supplies INA and can guide you on interchangeability.

If you have the bearing part number, send it by WhatsApp or email and the team will reply promptly with a quote. If you are unsure of the designation, send the shaft, housing and width dimensions, and they will help you identify the NA ZW XL series or a suitable equivalent.
