The NTN WA series spherical roller bearing is a double-row self-aligning bearing designed to support high radial loads and axial loads in both directions. Its spherical outer raceway and brass cage allow compensation of angular misalignment between shaft and housing, making it ideal for applications with shaft deflection or mountings where perfect alignment is not guaranteed. It is used in heavy machinery, conveyors, mills, and industrial equipment requiring robustness and durability.

The WA series designation is interpreted as follows: the prefix WA indicates a special execution with brass cage and specific features for demanding applications. The numbers that follow (for example, 22208, 22209, 22210) correspond to the size code according to ISO standards, where the first two digits indicate the dimension series and the last two the bore diameter. The suffixes EALLSD and 1/8A refer to construction variants: E indicates a high-strength machined brass cage, A indicates an optimized internal design, LL denotes special sealing, SD relates to lubrication grooves or holes, and 1/8A specifies a particular clearance or tolerance. These codes ensure the bearing meets precise mounting and operating requirements.

In Argentine industry, WA series spherical roller bearings are used in mining equipment, cement plants, aggregate processing plants, belt conveyors, flour mills, and food industry machinery. Their ability to withstand heavy loads and misalignment makes them common in gearboxes, high-flow pumps, industrial fans, and transmission shafts. They are also found in the steel sector and paper manufacturing, where working conditions are severe and reliability is required.

To correctly select a bearing from this series, consider the radial and axial load it must support, the rotational speed, and environmental conditions. The LL sealing protects against contaminant ingress and lubricant loss, making it recommended in dusty or humid environments. Verify the appropriate internal clearance for your application: excessive clearance can generate vibrations, while insufficient clearance raises temperature. During mounting, ensure initial alignment within allowable limits and use appropriate methods (hydraulic press or induction heating) to avoid damage to the raceways. Lubrication must be as specified by the manufacturer, with the correct quantity and frequency.

Spherical roller bearings are interchangeable between different brands as long as the main dimensions (bore diameter, outside diameter, and width) and execution type match. When seeking a replacement, compare tolerances, internal clearance, and sealing features. The NTN WA series may have equivalents in other brands with similar designations, but it is essential to verify that load and speed conditions are compatible. If in doubt, the complete code of the original bearing is the best reference to find the right part.
