Angular Contact Ball Bearing Pair, 80x125x22 mm, 30° Contact Angle, Open, Chrome Steel (2 pcs)

This is a pair (2 pcs) of NSK 7016A single-row angular contact ball bearings, 80 mm bore x 125 mm outside diameter x 22 mm width per bearing. In NSK nomenclature the A suffix denotes a 30° contact angle, which gives high axial capacity in one direction alongside radial load. Each bearing is rated 55.0 kN dynamic (Cr) and 53.0 kN static (C0r), with limiting speeds of 5,600 rpm on grease and 7,500 rpm on oil, and the effective load centre sits 40.6 mm from the face. Chrome-steel rings and balls, open (unsealed) construction, standard precision class. Angular contact bearings of this type generate an axial component under radial load, so they are normally installed in pairs – back-to-back (DB) for rigidity, face-to-face (DF), or tandem (DT) for shared one-direction thrust. Buyer note on contact angle: the 80x125x22 mm envelope is shared with NSK 7016C (15°) and SKF 7016 ACD (25°), but those are different contact angles and are not interchangeable where stiffness or preload matters. Made in Japan.
