The NTN HK series needle roller bearing is a single-row radial bearing with a steel outer ring and a cage of guided needles. Its very reduced section design allows it to be mounted directly on hardened and ground shafts, without an inner ring, which saves radial space and simplifies the assembly. It is used in applications where load capacity must be combined with a minimum outside diameter, such as transmissions, power tools, textile machines and automation equipment.

The HK series designation is read as follows: the letters HK identify a needle roller bearing with a stamped outer ring and no inner ring. The numbers that follow indicate, in millimeters, the bore diameter and the width: for example, HK0306FT2 corresponds to a 3 mm bore and a 6 mm width, while HK0408FT2 has a 4 mm bore and an 8 mm width. The FT2 suffix refers to an execution with a steel cage and a particular seal. Learn more about this series and its variants by consulting MR Accesorios Industriales.

In Argentine industry, HK series needle roller bearings are found in power transmission equipment, pumps, compressors, machine tools, textile equipment, industrial printers and white goods appliances. Their low profile makes them ideal for compact gearboxes, where radial space is critical. They are also used in conveyor rollers, cams and joints that require oscillating movements with high rigidity.

To correctly select an HK bearing, take into account the radial load, the speed and the environmental conditions. Since they do not have an inner ring, the shaft must have adequate surface hardness and a fine roughness to serve as a raceway. The FT2 seal protects against dust and moisture, but check the lubrication: these units usually come with factory grease and may require relubrication depending on the service. Alignment between shaft and housing is key to avoid lateral stresses.

NTN HK series needle roller bearings are interchangeable with those of other brands that follow the same dimensional nomenclature. If you have the code from another company, we can tell you the exact equivalent. We can also quote the size you need if you send us the shaft diameter, the outside diameter and the width. Interchangeability is based on standardized dimensions, not on each manufacturer's code.
