The NSK K series self-aligning ball bearing is a double-row self-aligning ball bearing with a tapered bore, which compensates for angular misalignment between shaft and housing. It is used in applications where the shaft may flex or where assembly is not perfectly parallel, such as fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and helps you choose the correct part number for your equipment.

The K series designation is read with the basic number followed by the letter K, which indicates a tapered bore. For example, 1204 K, 1205 K and 1206 K correspond to self-aligning ball bearings with a tapered bore diameter. The K suffix is the key to identifying that assembly requires an adapter sleeve or a tapered shaft. If the part number does not include K, the bore is cylindrical.

These bearings are used in equipment where there is misalignment or shaft flex: industrial fans, centrifugal pumps, conveyors, mixers, agricultural machinery and belt drives. In Argentina, they are common in the food, chemical and cement industries and in aggregate processing plants. Their self-aligning capability reduces wear and extends the service life of the assembly. MR Accesorios Industriales sells them for replacement and maintenance.

To select the correct bearing, take into account the load, speed and type of assembly. The K series with tapered bore is mounted on tapered shafts or with adapter sleeves; verify the taper and the locking system. Proper lubrication and sealing are critical: choose the lubricant according to temperature and environment, and consider seals if there is dust or moisture. Initial alignment is important, although the bearing tolerates misalignment. Consult MR to determine the best option.

NSK K series self-aligning ball bearings can be interchanged with those from other brands that follow the same dimensional designation. When looking for equivalents, compare the bore, outer diameter and width, as well as the bore type (tapered). If you have the part number from another brand, MR will indicate the equivalent NSK reference. Interchangeability is common in catalogue bearings, but always verify tolerances and internal clearance.
