3318 A / 3318A Angular Contact Ball Bearing 90x190x73 mm
Angular contact ball bearing 3318 A/C3, 90x190x73 mm; C0 Clearance; Shaft Mount; Double Row of angular contact ball bearing; Steel Cage Material; Open Enclosure; Relubricatable.
Double row angular contact ball bearings, with seals or shields, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Depending on the sealing execution, they can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.
