The SKF cam roller of the RSTO XTN series is a support roller designed to withstand radial loads in cam and guidance mechanisms. Its construction without an inner cage and with XTN sealing makes it suitable for applications requiring rigidity and protection against contaminants. It is used in transmission, handling and industrial automation systems, where rolling motion must be precise and long-lasting.

The RSTO XTN series designation is interpreted as follows: the letters RSTO identify a structural-type support roller, without an inner cage, with an outer raceway. The number that follows indicates the outer diameter in millimeters, for example, in RSTO 8 XTN it corresponds to 8 mm. The XTN suffix indicates a special double-lip seal that protects against dust and moisture, in addition to lifetime lubrication. This nomenclature allows you to quickly identify the size and sealing characteristics.

In Argentine industry, these bearings are used in handling equipment, such as conveyor belts and linear guidance systems, as well as in machine tools, presses and automation devices. They are common in the food sector, where cleanliness and resistance to washdowns are critical, and in the metallurgical industry for feed and positioning mechanisms. Their ability to withstand radial loads and tilting moments makes them versatile in applications with oscillating movements or continuous rotation.

To correctly select an RSTO XTN cam roller, take into account the required outer diameter, the overall width and the load conditions. The XTN seal is suitable for dusty or humid environments, but verify compatibility with lubricants and cleaning products. During mounting, ensure precise shaft alignment and avoid impacts that could damage the seal lips. Lifetime lubrication simplifies maintenance, although in severe applications it may require relubrication.

Regarding equivalences and interchangeability, cam rollers from different manufacturers may differ in dimensions and load capacities. Although standards exist that standardize some series, it is always advisable to verify the technical specifications before substituting one brand for another. SKF is a brand that MR carries, which guarantees access to genuine products and technical advice to choose the best option for the application.
