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. Learn more about this series and its applications by consulting MR.
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.

Frequently Asked Questions
- What are the dimensions of the NSK 1216 K bearing?
- The NSK 1216 K bearing has a 80 mm bore, a 140 mm outside diameter and a 26 mm width (80 x 140 x 26 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 1216.
- What does the letter K mean in the bearing designation?
- The letter K indicates that the bearing has a tapered bore. This allows it to be mounted on a tapered shaft or with an adapter sleeve, which facilitates adjustment and removal. It is important to verify the shaft taper or use the appropriate adapter sleeve.
- Where are K series self-aligning ball bearings used?
- They are used in equipment with shafts that may become misaligned, such as fans, pumps, conveyors and agricultural machinery. Their self-aligning capability compensates for small angular deviations and reduces wear in demanding industrial applications.
- How do I request a quote for an NSK K series bearing?
- Write to us on WhatsApp with the complete bearing part number, for example 1205 K, and we will quote it for you promptly. If you do not have the part number, send us the shaft and housing dimensions, or the equipment model, and we will advise you.
