Name: 22205EAW33
SKU: 22205EAW33-SNR

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

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 offers as standard, unsurpassed endurance and longevity.
