SKF NJ MA series cylindrical roller bearings are components designed to withstand high radial loads and high speeds, with a robust construction that makes them suitable for demanding machinery. They are used in equipment where precision and durability are critical, such as gearboxes, pumps and transmission systems. At MR Accesorios Industriales we sell and distribute this SKF line in Buenos Aires, Argentina, and we advise you so you can choose the right part number for your application.
The designation of these bearings is interpreted as follows: the letters NJ identify the cylindrical roller series, the number that follows indicates the dimension series and the bore size, and the suffix MA distinguishes a construction variant within the family. For example, NJ 248 MA and NJ 1060 MA correspond to different bore sizes and outside diameter series. To order the exact part number, send us the full reference shown on your equipment or drawing.
These bearings are used in industries in Argentina such as metallurgy, cement, mining and food processing. They are found in speed reducers, gearboxes, centrifugal pumps, industrial fans and machine tools. Their ability to handle significant radial loads and minimal misalignment makes them common in gear transmissions and in rotating equipment for continuous processes.
To select the right bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Assembly requires rigorous cleanliness, correct alignment of the supports and adequate lubrication according to the operating conditions. The NJ MA series is mounted with fits recommended by the manufacturer for the bore and the shaft; respecting the tolerances prevents premature failures.
When looking for equivalents from other brands, it is common to find part numbers that share the basic designation but differ in suffixes or construction details. Therefore, if you bring us a part number from another brand or an unidentified part, at MR we will tell you the compatible alternative or send you a quote for the SKF part number you need. Interchangeability between brands must always be verified against the dimensions and load capacity.
If you already have the part number of your SKF NJ MA bearing, write to us on WhatsApp and we will send you a quote shortly. We can also help if you need advice to identify the correct reference from the housing or shaft dimensions. At MR Accesorios Industriales we work so you can find the part your machine needs.
