The SKF NKIS series needle roller bearing is a radial bearing with an inner ring and steel cage, designed to withstand high radial loads in reduced spaces. It is used in applications where the radial section is limited and high load capacity is required, such as machine tools, transmission equipment and industrial mechanisms. MR Accesorios Industriales supplies this series with the backing of more than 80 years in the Argentine market.

The designation of the NKIS series is interpreted as follows: the letters NK indicate a needle roller bearing with inner ring, the I indicates that the inner ring is integrated, and the S corresponds to the steel cage. The number that follows, as in NKIS 17, NKIS 20 or NKIS 25, identifies the bore diameter. The series ranges from NKIS 17 to NKIS 50, with standardized dimensions for each size. When choosing, verify that the part number matches the dimensions of your shaft and housing.

These bearings are used in industries such as metalworking, food, textile and plastics. They are common in gearboxes, pumps, compressors, machine tools and power transmission equipment. In Argentina, they are found in production lines, conveyors and agricultural machinery. Their compact design allows them to be mounted in spaces where other bearings do not fit, while maintaining high radial load capacity.

To select the right bearing, take into account the radial load, rotation speed and environmental conditions. Sealing is essential: if there is dust or moisture, consider additional protections. Lubrication must be suitable for the working speed and temperature. During mounting, ensure correct alignment between shaft and housing to avoid undue axial loads. The steel cage provides robustness and heat dissipation.

Regarding equivalents, needle roller bearings with inner ring from other brands can be interchanged if the dimensions and load capacity match. Always verify tolerances and internal clearance. The SKF NKIS series is a reliable reference, but there are alternatives on the market. Consult us if you need help finding the right replacement.
