A drawn steel outer ring, a steel cage and a row of small cylindrical needles make up the NTN HK series bearing. It runs directly on a hardened, ground shaft instead of an inner ring, which keeps the radial envelope small while carrying high radial loads. Machine tools, motion equipment and power transmission assemblies are typical homes for it.

The code itself tells you the size. HK marks the design type, then two digits give the bore and two more give the width: HK2816CT is a 28 mm bore by 16 mm width, HK3012CT is 30 mm by 12 mm, HK3516CT is 35 mm by 16 mm and HK4016CT is 40 mm by 16 mm. The CT suffix stands for characteristics of this particular variant. When specifying, begin with the shaft diameter, then confirm the width the housing can accept.

Because the profile is so low, these bearings fit where a deep groove ball bearing would not. They appear in pulleys, rollers, pumps, compressors, conveyor belts, packaging machinery, elevators and belt drives, and across metalworking, food, textile and logistics operations. With no inner ring, the shaft doubles as the raceway, which trims both design work and assembly weight.

Mounting depends on the shaft. It has to be hard enough and finished smoothly, since the needles roll straight on it, and shaft-to-housing alignment must be tight because misalignment speeds up wear. Grease or oil both work as lubricant, chosen by speed and operating temperature. Keep the assembly sealed to hold lubricant in and contaminants out, adding radial shaft seals or covers where dust or moisture is present. The steel cage keeps the needles in line and permits high speeds at low friction.

Standardized envelope dimensions mean HK series bearings interchange between manufacturers as long as bore, outer diameter and width line up, and the same holds for equivalent series in other catalogs. To replace a worn unit, read the full code off the outer ring or measure the shaft and housing. Send either one and MR Industrial Accessories LLC will quote the exact reference or a compatible alternative, and can also help identify a part from your shaft and housing dimensions. We serve customers throughout the United States and in several Latin American countries.
