NSK cylindrical roller bearings of the NU series with EM suffix are components designed to withstand high radial loads and high speeds, with a separable construction that facilitates mounting and maintenance. They are used in equipment where the shaft must move axially within the housing, such as electric motors, pumps, gearboxes and continuous process machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the correct code.

The designation of these bearings is read in parts. The letters NU indicate that the outer ring has two ribs and the inner ring has none, which allows axial displacement of the shaft relative to the housing. The number that follows, as in NU222EM, NU224EM or NU230EM, identifies the dimensional series and size. The suffix EM indicates a machined brass window cage, suitable for higher speed and load demands. Recognizing each block avoids confusion when ordering a replacement.

These bearings are used in Argentine industries where there are significant radial loads and shafts that expand: electric motors, centrifugal pumps, industrial fans, conveyor belts, gearboxes and machine tools. They also appear in mining, cement, paper and food equipment. In all cases, the capacity of the NU series with EM cage makes them suitable for continuous service with adequate lubrication and careful alignment between shaft and housing.

For selection and mounting, take into account the type of sealing or protection: if the environment has dust or moisture, it is advisable to evaluate variants with seals or deflectors. Internal clearance and lubrication must be defined according to operating speed and temperature. Alignment between supports is critical: excessive misalignment shortens bearing life. During mounting, avoid striking the rings and use appropriate tools to prevent damage to the raceways or cage.

Interchangeability between brands is handled by designation and dimensions: a code from another company with the same series and suffix is usually interchangeable, but always verify the cage, clearance and tolerances before replacing. If you bring the code of the original part or an unidentified sample, at MR Accesorios Industriales we will indicate the compatible alternative and quote the exact size you need.

To proceed with your inquiry, send us via WhatsApp the complete code, for example NU226EM, or the shaft and housing measurements. We will quote shortly and guide you on the variant that best suits your equipment. MR Accesorios Industriales, Buenos Aires, Argentina, more than 80 years supporting industry.

Frequently Asked Questions

What does the EM suffix mean in an NU bearing?
The EM suffix indicates that the bearing has a machined brass window cage, which better withstands high loads and speeds than a standard cage. It is a useful reference for comparing with other brands and verifying interchangeability.
How do I request the correct size of an NU bearing?
Send me the complete code that appears on the part or on the drawing, for example NU224EM, or the shaft and housing measurements. With that we will quote the exact reference and confirm the variant that corresponds to your equipment.
Can I replace an NU bearing from another brand with an NSK one?
In general yes, if the series, number and cage suffix match. Dimensions and tolerances are standardized, but it is advisable to verify the internal clearance and cage type. If you have doubts, send us the original code and we will indicate the equivalent.
