The NNTR series from INA covers thick-walled cylindrical roller bearings built as support rollers. They handle heavy radial loads in both rotating and oscillating duty, mounting on a shaft or a stud, and are commonly found in linear guides, cam drives and conveying equipment. The thick outer ring lets them take impacts and combined stresses in tough machinery. MR Industrial Accessories LLC supplies this INA line across the United States, Canada, Mexico and South America, and can help you pin down the right part number.

Reading the code is straightforward. NNTR marks the double-row support roller family, and the digits after it give the outside diameter in millimeters: NNTR50 is a 50 mm outside diameter roller, NNTR60 is 60 mm, and so on. That makes sizing quick, without extra tables. Where suffixes appear, they can point to sealing, cage or tolerance variants, so it pays to confirm against the data sheet before you request a quote.

Typical installations include linear motion equipment such as machine tool guides, presses, conveyor belts and lifting systems. Cam applications and support rollers on large sliding doors, cranes and mining equipment are also common. Because the rollers tolerate high radial loads and tilting moments, they suit assemblies with tight space and significant load requirements.

When selecting, work from the outside diameter, the overall width and how the roller will be mounted. NNTR rollers can sit directly on the shaft or run on a stud, depending on the design of the equipment. Check alignment and radial clearance so parasitic loads do not appear. Lubrication has to match the operating speed and temperature, and in dirty environments sealed variants are worth evaluating. Use the right tools during assembly to keep the raceways intact.

Dimensional equivalents from other European or Asian brands can often replace INA rollers when the main dimensions and load capacities line up. Tolerances and heat treatment are not necessarily the same across manufacturers, so it is worth confirming any substitution with a specialist. Our team can review interchangeability and source the exact part number your equipment calls for.

If you already have the part number, send it over on WhatsApp or by email and we will reply promptly with a quote. We can also help identify the roller from a sample or from the mounting measurements. Our team supports customers in the United States, Canada, Mexico and South America.
