When radial room is limited, the INA NK series offers a single-row needle roller bearing that runs directly on a hardened and ground shaft. There is no inner ring, so the shaft itself serves as the raceway. This low-section design delivers solid load capacity and rigidity in a compact envelope, which makes it a common choice for machine tools, gearboxes, pumps, textile machinery and general transmissions. MR Industrial Accessories supplies this INA line to customers throughout the United States and in several Latin American countries.

Reading an NK designation is straightforward once you know the blocks. The letters NK mark a needle roller bearing without an inner ring and with a machined outer ring. Next comes the bore diameter, then a slash, then the width. In NK5/10-TV-XL, the 5 is the bore diameter and the 10 is the width. The suffix TV points to a reinforced polyamide cage; XL identifies the longer service life version within the line. NK8/16-TV-XL follows the same pattern and differs only in its dimensions.

These bearings suit positions where radial space is at a premium: gearboxes, oil pumps, compressors, machine tool spindles, textile and food industry equipment, and agricultural machinery transmissions. For maintenance teams, replacing a complete bearing of the same section often simplifies the repair without any machining of the housing.

Selection depends on the shaft, since it acts as the raceway. It has to be hardened and ground, with the appropriate hardness and roughness. Check alignment between shaft and housing as well, because these bearings do not tolerate misalignment well. Grease or oil lubrication is possible depending on the assembly, and sealing is handled with external radial shaft seals or with sealed variants of the line. Correct internal clearance helps prevent overloads and supports the life of the assembly.

Interchange between manufacturers works by dimensions and cage type, not by commercial code. To replace an INA bearing with another brand, compare bore diameter, outer diameter, width, cage type and version. Suffixes do not always match across manufacturers, so dimensional verification before mounting is essential.
