The SKF cam follower of the NUKR XA series is a cylindrical roller bearing with an integrated stud, designed to withstand high radial loads and moderate speeds in cam and guide applications. Its robust construction and axial sealing make it suitable for machinery requiring high load capacity and resistance to contamination. MR Accesorios Industriales sells this series as part of its SKF bearing line, with more than 80 years of experience in the field.
The designation of the NUKR XA series is interpreted as follows: the letters NUKR indicate a cylindrical roller cam follower with a polyamide cage and axial sealing; the number that follows (35, 40, 52, 62, 90 in the examples) corresponds to the outer diameter of the roller in millimeters; and the suffix XA indicates a design with a hexagonal hole at the end of the stud to facilitate mounting and lubrication. This nomenclature allows quick identification of the size and main characteristics of the roller.
These rollers are used in a wide variety of industrial applications in Argentina, such as drive cams in machine tools, linear guides in automation equipment, support rollers in conveyors, and in the automotive industry for assembly lines. They are also present in the food industry, where components resistant to corrosion and frequent washdowns are required, and in the metallurgical industry for rolling systems in furnaces and rolling mills.
To correctly select a NUKR XA cam follower, it is essential to consider the radial and axial load it must withstand, as well as the rotation speed and environmental conditions. The axial sealing protects against the entry of contaminants, but its compatibility with the lubricant used must be verified. During mounting, ensure precise alignment of the stud and avoid impacts that could damage the rollers or raceways. Proper lubrication extends the service life of the bearing.
Regarding equivalences and interchangeability, SKF cam followers of the NUKR XA series can be replaced by products from other manufacturers that follow the same dimensional and load capacity standard, such as those from INA, IKO or NTN. However, it is important to verify tolerances and the type of sealing, as they may vary between manufacturers. Always consult the technical specifications before replacing a component to ensure optimal operation.

Frequently Asked Questions
- What does the XA suffix mean in NUKR rollers?
- The XA suffix indicates that the roller has a hexagonal hole at the end of the stud, which facilitates mounting and allows relubrication through the stud. This feature is common in applications where access is limited.
- How do I choose the right NUKR roller size?
- The number in the designation (for example, 35, 40) corresponds to the outer diameter in millimeters. To choose, consider the radial load, available space and operating speed. Consult us with your application data and we will advise you.
- Are NUKR XA rollers interchangeable with other brands?
- Yes, they can be interchangeable with rollers from other brands that meet the same dimensions and load capacities, such as INA or IKO. Always verify tolerances and the type of sealing before replacing.
