INA NAO series needle roller bearings are radial bearings with a very small cross-section, designed to withstand radial loads in spaces where a ball or roller bearing does not fit. They are widely used in machine tools, transmission equipment and compact mechanisms. MR Accesorios Industriales sells this INA line in Buenos Aires, Argentina, and helps you choose the correct part number for your application.
The NAO series designation is read by its number, which identifies the size within the series. That number identifies the bearing's size within the series and correlates with the main dimensions. When requesting a quote, provide the complete part number shown on the drawing or on the part, so we can give you the exact equivalent. If you have doubts, send us a photo of the marking and the housing measurement.
These bearings are used in spindles, camshafts, pumps, compressors, textile machines, packaging equipment and transmission mechanisms in general. In Argentina you will find them in maintenance workshops, food, metallurgical and plastics plants, where radial space is critical and high load capacity is needed in a small volume. They are also used in repairs of imported machines, where interchangeability by size is key.
To correctly select an NAO, take into account the shaft and housing diameters, the overall width and the radial load it will withstand. Check the type of sealing or protection the environment requires: if there is dust, chips or humidity, additional protection is advisable. Assembly is done with the appropriate fit on the housing and shaft, without striking the cage, and with clean, compatible lubrication. Aligning the supports prevents stresses that shorten the bearing's life.
As for equivalents, needle roller bearings are identified by their main dimensions and their design type. When changing brands, it is not enough for the part number to look similar: you must compare bore diameter, outside diameter, width and load capacity. At MR Accesorios Industriales we advise you to find the INA option that best suits your equipment, respecting the original dimensions and the mounting type.
If you already have the NAO part number or the bearing measurement, write to us on WhatsApp and we will quote you shortly. At MR Accesorios Industriales we work with the INA line and other brands so that you find the right solution without hassle. Send us the details of your application and we will reply with the alternative you need.
