The SKF NX ZTN series needle roller bearing is a single-row needle roller bearing designed to withstand high radial loads in very tight spaces. Its compact construction and high load capacity make it ideal for applications where axial and radial space is limited. It is used in machine tools, transmissions, pumps and industrial equipment in general. MR Accesorios Industriales carries this official brand and advises you so you can choose the right bearing for your application.

The NX ZTN series designation is interpreted as follows: the letters NX identify the series of single-row needle roller bearings with compact dimensions; the number that follows indicates the bore diameter, for example in NX 7 ZTN the 7 corresponds to a 7 mm bore diameter. The ZTN suffixes indicate that the bearing incorporates an inner ring with a flange and a reinforced plastic cage, which facilitates mounting and improves needle retention. This nomenclature allows you to quickly identify the main characteristics of the product.

This type of bearing is used in applications that require high radial load capacity in a minimal space. In Argentine industry, it is commonly found in machine tool spindles, gearboxes, water and oil pumps, compressors, electric motors and automation equipment. It is also used in the automotive sector, in components such as camshafts and transmissions. Its design allows it to withstand high radial loads and moderate speeds, with an excellent ratio between size and load capacity.

To correctly select an NX ZTN needle roller bearing, take into account the bore diameter, the required load capacity and the lubrication conditions. It is essential to check the sealing: if the environment has dust or moisture, consider variants with seals. Mounting must be carried out with suitable tools to avoid damaging the needles and the cage. The alignment between the shaft and the housing must be precise to avoid additional loads. Lubrication can be grease or oil, depending on the speed and working temperature.

As for equivalents and interchangeability, needle roller bearings from different manufacturers may have different designations but standardized dimensions. It is important to compare the main dimensions (bore diameter, outer diameter and width) and the load and speed characteristics. SKF is a globally recognized brand, and its products are often interchangeable with those of other manufacturers that follow the same dimensional standards. Always consult the technical specifications before replacing one bearing with another of a different brand.
