When a machine point has to carry radial and axial forces at once and there is barely room for one bearing, the INA NX7-TV-XL is a common answer. It is a combined needle roller bearing: one row handles the radial load, a second row takes the axial load. MR Industrial Accessories supplies this brand and helps you match the reference to your application.

Reading the code helps when you compare options. NX marks the combined needle roller bearing family. The 7 is the shaft diameter in millimetres. TV tells you the cage is reinforced polyamide, a fit for moderate temperatures and higher speeds. XL is INA's tag for the optimised version of the series. Together, TV and XL describe a compact bearing that needs little attention once it is installed correctly.

Typical service points include machine tools, pumps, compressors, transmission assemblies and clutch systems. Because one unit covers both load directions, designers avoid stacking two separate bearings, which saves axial space and simplifies the housing. Automotive, metalworking and food processing operations are among the sectors that use this arrangement.

Selection comes down to four inputs: shaft diameter, the radial and axial loads involved, rotation speed and the surrounding conditions. Alignment at mounting has to be accurate, and lubrication must be right. Grease or oil both work, depending on the duty. Where dust or moisture is present, add extra protection. The polyamide cage performs well across high speed ranges.

Cross-brand substitution deserves caution. Similar designations exist elsewhere, yet dimensions and capacities do not always line up, so a direct swap is risky. Confirm the measurements and speak with a specialist before committing. MR Industrial Accessories can point you to the right reference in its range.
