The NTN HK series needle roller bearing is a single-row radial bearing without an inner ring, with a steel cage and sealing. Its compact design handles high radial loads in very small radial spaces, making it ideal for applications where the outer diameter is limited. It is used in transmissions, electric motors, pumps and general machinery. MR Accesorios Industriales sells this series with NTN quality and the backing of more than 80 years in the Argentine market.

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 the bore diameter and the width of the part. For example, HK2538ZWD corresponds to a bearing with a 25 mm bore and 38 mm width, while HK3038ZWD has a 30 mm bore and the same width. The ZWD suffix indicates a configuration with sealing and specific series features. Learn more about this nomenclature by contacting MR Accesorios Industriales.

These bearings are used in a wide variety of industrial equipment in Argentina: gearboxes, electric motors, hydraulic pumps, compressors, machine tools and power transmission equipment. Their ability to handle radial loads in confined spaces makes them common in the automotive, metallurgical, food and construction industries. They are also found in linear motion applications and in rollers of textile and printing machines.

To select the right bearing, take into account the shaft diameter, the radial load and the lubrication and sealing conditions. The HK ZWD series includes sealing that retains lubricant and protects against contaminants, so it is suitable for dusty or humid environments. During mounting, check alignment and avoid impacts that could damage the needles. Proper lubrication, with grease or oil depending on the application, extends the service life of the bearing.

NTN HK series needle roller bearings are interchangeable with those of other brands that follow the same dimensional nomenclature. If you need to replace a bearing from another brand, you can send us the part number or the shaft and housing dimensions to identify the equivalent. At MR Accesorios Industriales we advise you so you can find the option compatible with your equipment while maintaining the original performance.
