Spherical roller bearing, pressed steel cage, groove and lubrication holes on outer ring, tapered bore 1:12, non ISO width, contact seals on both sides

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 EUROPE offers as standard, unsurpassed endurance and longevity.
