The NSK spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, with the particular feature of accommodating angular misalignment between shaft and housing. Its double row of rollers, guided by a spherical raceway in the outer ring, allows it to adapt to shaft deflection without losing load capacity. It is used in equipment where perfect alignment is not guaranteed, such as conveyors, mills, pumps and heavy machinery. MR Accesorios Industriales sells the NSK brand and advises you on choosing the correct part number.

The series designation combines numbers and letters that identify the size and variants. For example, in *21319CAME4 and *22228CAME4, the initial digits indicate the dimension series; the suffix CAME4 indicates the internal design with machined brass cage, center guide and special treatment. In *22230CAME4 and *22232CAME4 the pattern repeats: the base number defines the diameter and width, while the final letters specify characteristics such as cage type and internal clearance. Knowing these suffixes is key to ordering the exact replacement.

These bearings are used in Argentine industries such as cement, mining, steel, paper and food. They are present in conveyor belts, ball mills, crushers, centrifugal pumps, industrial fans and paper machines. Their ability to withstand misalignment makes them ideal for equipment subject to vibration or deflection, where other bearings would fail prematurely. In pulp plants, for example, they are used in dryers and presses, while in mining they are mounted on screens and mills.

To select correctly, take into account radial and axial load, rotation speed and environmental conditions. Sealing is essential: in dusty or humid environments, choose variants with seals or protective plates. Lubrication must be adequate: high-viscosity grease for high temperatures or circulating oil in critical applications. Mounting requires initial alignment and a fit that allows self-alignment; avoid striking the rings. Internal clearance must be the specified one to compensate for thermal expansion.

Equivalences between brands are possible if dimensions and load capacity are compared. An NSK bearing can be replaced by one from another brand with the same basic designation, but check the suffixes, as they may vary the clearance, cage or heat treatment. At MR Accesorios Industriales we quote the exact part number or size you need.
