NSK offers its high-capacity angular contact ball bearings featuring a pressed steel cage and larger ball bearings, and delivering a longer life.
By using larger ball sizes, these angular contact ball bearings can deliver 1.2 – 1.6 times longer fatigue life than similar bearings. Both side bores of the outer ring are also larger than conventional bearings, while both side shoulder diameters of the inner ring are smaller. This increased clearance between the inner ring and cage leads to improved oil flow through the bearing.
There are five bearings in the BEAW range with bore sizes from 60 to 80 mm.
