The SKF needle roller bearing of the HK series with RS suffix is a drawn cup type bearing, with a steel cage and elastomer seal on one or both sides. It is used to support radial loads in very small radial spaces, where a ball bearing does not fit. It is common in power transmission applications, household appliances, power tools and agricultural machinery.

The designation HK … RS is read as follows: HK indicates that it is a drawn cup needle roller bearing, without inner ring. The number that follows, for example in HK 0810 RS, are the dimensions: the first two digits are the bore diameter in millimeters and the next two are the width. In HK 0810 RS the bore is 8 mm and the width is 10 mm. The suffix RS indicates an elastomer seal on one side; 2RS indicates seals on both sides. Examples in the series include HK 0812.2RS, HK 1012 RS, HK 1014.2RS, HK 1214 RS, HK 1216.2RS, HK 1616.2RS and HK 2020.2RS.

These bearings are used in applications where radial space is critical and loads are moderate. In Argentina they are found in gearboxes, electric motors, pumps, compressors, textile machines, packaging equipment and agricultural machinery. They are also common in household appliances such as washing machines and in portable power tools. Their drawn cup design allows them to be mounted directly on the shaft, without the need for an additional inner ring, which simplifies the assembly design.

To select the correct bearing, take into account the shaft diameter, the available width and the type of seal. The HK series with RS or 2RS suffix is already sealed from the factory, which protects against dust and moisture, but does not replace good lubrication. During mounting, make sure the shaft has the proper hardness and roughness to serve as a raceway. Alignment between the shaft and the housing is essential to avoid parasitic axial loads. If the environment is highly contaminated, consider adding external seals.

Regarding equivalents, drawn cup needle roller bearings with seals are available from several brands under similar designations, but they are not always directly interchangeable. The main dimensions (bore diameter, outer diameter and width) usually match, but load capacity, seal type and tolerance may vary. Always verify the complete part number and the manufacturer's specifications before replacing one bearing with another of a different brand.
