The INA NKI-TW-XL series needle roller bearing is a radial bearing with machined inner and outer rings, polyamide cage and high load capacity needles. It is used where radial space is limited and high loads must be supported with precision. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with more than 80 years of experience in power transmission components.

The NKI-TW-XL designation reads as follows: NKI identifies a needle roller bearing with machined inner and outer rings, suitable for high radial loads. The number after NKI indicates the bore diameter and the width series; for example, NKI35/20-TW-XL has a 35 mm bore diameter and 20 mm width. The TW suffix indicates a reinforced polyamide cage, and XL designates the current product generation within the INA catalogue. Knowing these codes allows you to identify the part without ambiguity.

These bearings are used in machine tools, pumps, compressors, gearboxes, packaging equipment and transmission systems in Argentine industrial plants. Their compact construction makes them ideal for gearboxes, pulleys and rollers where axial and radial space is limited. They are also found in mining, food processing and automation equipment, whenever high rigidity and load capacity are required in a small volume.

To select the correct bearing, take into account the shaft diameter, radial load and lubrication conditions. The NKI series supports grease or oil lubrication; verify the viscosity and the application method. Mounting must ensure alignment between shaft and housing, with fits that prevent deformation. The TW cage tolerates moderate speeds and operating temperatures within the polymer's limits. Proper sealing extends service life in dusty or humid environments.

Regarding equivalents, needle roller bearings with machined inner and outer rings from other brands can be interchanged if main dimensions, tolerances and load capacity match. Bore diameter alone is not enough: width, fillet radius and cage type must be compared. For replacements, it is always advisable to verify the complete designation and consult a specialist. MR Accesorios Industriales can advise you on alternatives within the INA line and other brands it supplies.
