NTN 23024EAW33C3 SPHERICAL ROLLER BEARING

Thanks to its two rows of symmetrical rollers and its self-aligning capability, this spherical roller bearing ensures reliable operation even in the presence of misalignment or shaft deflection. Of open design, it incorporates a stamped sheet steel cage, combining robustness and lightness. This product offers an excellent compromise between load capacity, durability and adaptability to complex industrial environments.

Characteristics :
This two-row roller bearing from NTN's ULTAGE range is designed to withstand high radial and axial loads in both directions. It naturally compensates for misalignment and shaft deflection thanks to its self-aligning ability. Its cylindrical bore allows simple and stable mounting, while the radial clearance C3 improves thermal endurance and adaptation to high rotational speeds. The stamped sheet steel cage, light and durable, reduces inertia and promotes high rotational speeds. The optimized surface finishes and the specific treatment applied in the ULTAGE range reduce friction, ensuring smooth operation at high speed. These innovations result in limiting speeds higher by 20% compared to conventional models.

Maintenance :
This model requires regular lubrication to maintain long-term performance. Not pre-lubricated, it must be paired with a grease or oil suitable for the load, temperature and speed conditions. Effective re-lubrication is made possible by an annular groove and lubrication holes integrated into the outer ring. It is essential to thoroughly clean external components before any re-greasing to limit the ingress of contaminants. In case of high temperature or exposure to particles, regular visual checks and rigorous maintenance are recommended to prevent premature wear.

Sealing :
This bearing is of the open type, i.e., it does not have integrated seals. This configuration facilitates visual inspection and greasing but also makes it more sensitive to external impurities such as dust, moisture or solid debris. It is therefore imperative to use it in a clean environment or to provide appropriate external protection. The presence of re-lubrication devices nevertheless helps extend its service life by ensuring good evacuation of particles and uniform distribution of the lubricant.
