NTN 22308EAKW33 SPHERICAL ROLLER BEARING

This spherical roller bearing from NTN supports heavy loads (axial and radial) in both directions, while compensating for misalignment. It is a preferred choice for heavy industrial applications under high combined loads.

Features :
Equipped with a two-row roller architecture, this spherical roller bearing ensures excellent distribution of radial and axial loads. Its 1:12 tapered bore allows precise mounting with clearance adjustment, improving stability and service life. The stamped steel cage guarantees optimal guidance of the rollers while facilitating lubrication. This spherical roller bearing naturally accommodates shaft deflection and misalignment, limiting stresses throughout the system. Thanks to ULTAGE® technology, the dynamic load capacity is considerably increased, making it a strategic choice for intensive use.

Maintenance :
This spherical roller bearing is not pre-lubricated. It requires regular lubrication with grease suitable for the loads, temperatures and rotational speeds. Precise re-lubrication via the lubrication holes provided on the outer ring helps extend the bearing's service life. In dusty or humid environments, careful cleaning of components is recommended before applying the lubricant. Thermal stability allows operation up to 200 °C, subject to compliant lubrication.

Sealing :
This roller bearing model features an open design, without integrated seals. While this offers notable advantages (heat dissipation, speed, efficiency...), it remains sensitive to external contaminants such as dust or moisture. It is necessary to provide external protection or increase maintenance frequency to maintain its performance.

Brand information :
NTN is a major global player in the field of bearings and precision mechanical solutions. Founded in Japan in 1918, the brand is distinguished by its technological expertise, rigorous quality standards and capacity for innovation. NTN is present in more than 30 countries and offers high-performance products for the automotive, industrial and aerospace sectors. Its ULTAGE® range embodies the pinnacle in terms of durability and reliability.

Key advantages :
- Integrated self-alignment compensating for misalignment and shaft deflection.
- Exceptional dynamic load capacity thanks to ULTAGE® technology.
- Long service life, significantly reduced maintenance interventions.
- Precise and quick mounting thanks to the tapered bore.
- Design optimized for effective lubrication and improved cooling.
- Stable performance at high temperatures up to 200 °C.

Applications :
This spherical roller bearing is particularly suitable for power transmissions, heavy-duty conveyors, crushers, industrial centrifuges, ventilation systems, mixers and railcar axles. Conversely, its use is less suitable in situations where loads are very light, where high precision is required or when particularly quiet operation is essential.
