The NSK MJ series needle roller bearing is a small-diameter cylindrical roller bearing designed to support radial loads in reduced mounting spaces. It is used when the available section is limited and high load capacity is needed relative to size. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and helps you identify the exact part number for your application.

The MJ series designation is read as a numeric code preceded by the letters MJ. Each number identifies a combination of dimensions and construction features. For example, MJ-361, MJ-451, MJ-471, MJ-551, MJ-571, MJ-651, MJ-681 and MJ-781 correspond to different sizes within the series. To select the correct bearing, you need to know the shaft diameter, the outer diameter and the width, or the complete part number shown on the drawing or on the original part.

These bearings are used in a wide variety of industrial applications in Argentina: machine tools, transmission equipment, pumps, compressors, electric motors, agricultural machinery and linear motion equipment. Their compact design makes them suitable for gearboxes, spindles and mechanisms where radial space is critical. They are also used in cam rollers and followers, where loads are predominantly radial.

For correct selection and mounting, take into account the type of seal required according to the environment (dust, humidity, chips), the internal clearance suited to the application, and lubrication: grease or oil depending on speed and working temperature. Alignment between the shaft and the housing is essential to avoid undue axial loads. Mounting must be carried out with suitable tools, without striking the rollers or raceways directly.

As for equivalents and interchangeability, needle roller bearings from different brands can be replaced if the main dimensions match (bore, outer diameter and width) and the load and speed conditions are suitable. It is always advisable to verify the original part number and tolerances. If you have a part number from another brand or an unidentified part, write to us on WhatsApp and we will indicate the compatible alternative or quote the exact part number you need.
