22209EG15W33C3

Spherical roller bearing, polyamide cage, groove and lubrication holes on outer ring

product label

The spherical roller bearing withstands significant loads and misalignments. This type of roller bearing is well adapted to harsh operating conditions: impacts or vibrations (crushers, vibrating screens, heavy handling, etc.). With the ULTAGE design, NTN-SNR offers as standard, unsurpassed endurance and longevity.
