NTN K series spherical roller bearings are self-aligning components with two rows of rollers, designed to withstand high radial loads and axial loads in both directions, even with misalignment between shaft and housing. They are used in heavy equipment where shaft deflection or mounting errors require self-aligning capability. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.

The K series designation is interpreted by the size number and the K suffix, which indicates a tapered bore with 1:12 taper. Examples 239/500K, 239/530K and 239/560K correspond to the 239 series with bore diameters expressed in millimeters (500, 530 and 560 mm respectively). The K suffix is key for mounting on tapered shafts or adapter sleeves, which facilitates adjustment and disassembly.

These bearings are used in core industries: steel, cement, mining, paper, cranes and heavy transmission equipment. In Argentina, they are commonly found in large gearboxes, mills, rotary kilns and conveyors. Their self-aligning capability makes them ideal for long shafts subject to deflection, where other rigid bearings do not tolerate misalignment.

For correct selection, take into account radial and axial load, rotation speed and environmental conditions. Sealing is critical in dusty or humid environments: choose configurations with seals or protective plates. Lubrication can be grease or oil, and internal clearance must be adjusted according to the application. When mounting with a tapered bore, verify the tightening of the adapter sleeve to achieve the proper residual clearance.

Regarding equivalences, NTN K series spherical roller bearings are interchangeable with those of other brands that follow the same ISO designation, such as SKF, FAG or NSK, provided dimensions and suffixes match. For replacements, it is essential to verify the complete part number and tolerances. If you have the part number from another brand, we will indicate the compatible alternative.
