The NTN WA series spherical roller bearing is a double-row self-aligning bearing designed to withstand high radial loads and axial loads in both directions. Its spherical outer raceway and brass cage allow it to compensate for 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 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 grooves or holes for lubrication, and 1/8A specifies a particular tolerance or clearance. These codes ensure that the bearing meets precise mounting and operation requirements.
In Argentine industry, WA series spherical roller bearings are used in mining equipment, cement plants, aggregate processing plants, conveyor belts, flour mills and machines for the food industry. Their ability to withstand heavy loads and misalignment makes them common in gearboxes, high-flow pumps, industrial fans and drive shafts. They are also found in the steel sector and in paper manufacturing, where working conditions are severe and reliability is required.
To correctly select a bearing from this series, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. The LL seal protects against the entry of contaminants and lubricant loss, so it is recommended in dusty or humid environments. Verify the internal clearance suitable for your application: excessive clearance can generate vibrations, while insufficient clearance raises the temperature. During mounting, ensure initial alignment within permissible limits and use appropriate methods (hydraulic press or induction heating) to avoid damage to the raceways. Lubrication must be as indicated by the manufacturer, with the correct quantity and frequency.
Spherical roller bearings are interchangeable between different brands as long as the main dimensions (inner diameter, outer diameter and width) and the type of execution match. When looking for a replacement, compare tolerances, internal clearance and sealing characteristics. The NTN WA series may have equivalents in other brands with similar designations, but it is essential to verify that the load and speed conditions are compatible. If in doubt, the complete part number of the original bearing is the best reference for finding the right part.

Frequently Asked Questions
- What does the WA series mean in NTN bearings?
- The WA series identifies spherical roller bearings with a special design, generally with a brass cage and optimizations for severe loads. The following numbers indicate the size according to ISO standards, and the suffixes detail features such as sealing, lubrication grooves and specific tolerances.
- How do I choose the right WA bearing for my machine?
- Consider the radial and axial load, the speed, the environment and the type of mounting. The LL seal protects in contaminated environments. Verify the internal clearance and make sure the dimensions match your shaft and housing. If you have the original part number, that is the ideal starting point.
- Are NTN WA series bearings interchangeable with other brands?
- Yes, as long as the main dimensions and the type of execution match. Compare tolerances, clearance and sealing. Interchangeability is not automatic: verify that the load and speed conditions are compatible. The complete part number helps find the correct equivalent.
