The SKF NX Z series needle roller bearing is a combined bearing that integrates a needle roller cage with an inner ring and a lateral seal. It is designed to withstand high radial loads in tight spaces, with a minimal outer diameter. It is used in applications where axial and radial space is critical, such as gearboxes, pumps and machine tools. MR Accesorios Industriales carries this series as part of its SKF bearing line.

The NX Z series designation reads as follows: the letters NX identify a needle roller bearing with an inner ring and a reduced section height; the final Z indicates that it has a lateral seal on one side. The numbers appearing in the examples, such as NX 10 Z, NX 12 Z, NX 15 Z, NX 20 Z and NX 25 Z, correspond to the shaft diameter or bore size, depending on the standard. The higher that number, the larger the bore diameter and load capacity. This series is available with different seal and tolerance combinations, but always maintaining the compact geometry.

Typical applications for this type of bearing include power transmissions, gear reducers, hydraulic pumps, compressors, textile machinery and automation equipment. In Argentina, it is found in the automotive industry, assembly lines, the metalworking sector and food and beverage plants. Its ability to run at high speeds and withstand considerable radial loads makes it suitable for shafts where space is limited and rigidity is required. It is also used in machine tools and linear motion equipment.

To correctly select an NX Z series needle roller bearing, take into account the shaft diameter, radial load and lubrication conditions. The Z seal protects against the ingress of contaminants and retains lubricant, making it advisable in dusty or humid environments. Check shaft and housing alignment to avoid parasitic axial loads. Lubrication can be with grease or oil, following the manufacturer's recommendations. During assembly, avoid striking the needle roller cage and make sure the inner ring is properly seated.

Regarding equivalences and interchangeability, needle roller bearings with inner ring and seal from different brands may differ in tolerances and seal shape. Although the main dimensions usually follow international standards, it is not advisable to assume that a part number from another brand is a direct replacement without verifying the specifications. MR Accesorios Industriales carries SKF as a brand, and can advise you on compatibility with other brands it also distributes. It is always advisable to consult a specialist before substituting one bearing for another from a different manufacturer.
