The INA NNTR series support roller is a thick-walled cylindrical roller bearing designed to withstand high radial loads in rotating and oscillating movements. It is mounted on a shaft or stud and used as a support roller in linear guides, cams and conveying systems. Its robust construction allows it to absorb impacts and combined stresses in demanding machinery. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with technical advice to select the correct part number.

The NNTR series designation reads directly: the letters identify the double-row support roller family, and the number that follows indicates the outside diameter in millimeters. For example, NNTR50 corresponds to a roller with a 50 mm outside diameter, NNTR60 to a 60 mm one, and so on. This nomenclature allows you to quickly locate the size you need without resorting to additional tables. If the part number includes suffixes, these may indicate sealing, cage or tolerance variants; in those cases, it is advisable to check the data sheet before requesting a quote.

In Argentine industry, INA NNTR series support rollers are used in linear motion equipment, such as machine tool guides, presses, conveyor belts and lifting systems. They also appear in cam applications and support rollers for large sliding doors, cranes and mining equipment. Their ability to withstand high radial loads and tilting moments makes them suitable for assemblies where space is limited but load requirements are significant.

To select the right roller, take into account the required outside diameter, the overall width and the type of mounting. The NNTR series can be mounted directly on the shaft or by means of a stud, depending on the equipment design. It is essential to check the alignment and radial clearance to avoid parasitic loads. Lubrication must be suitable for the operating speed and temperature; in contaminated environments, it is advisable to evaluate sealed variants. Assembly must be carried out with appropriate tools so as not to damage the raceways.

INA support rollers can be interchanged with equivalent products from other European or Asian brands, provided that the main dimensions and load capacities match. However, tolerances and heat treatment may vary between manufacturers, so it is advisable to confirm the equivalence with a specialist. At MR Accesorios Industriales we can advise you on interchangeability and source the exact part number your equipment needs.
