A Fafnir 2MM216WI-DUL matched duplex pair of super-precision single-row angular contact ball bearings. Each bearing is 80 mm bore, 140 mm outside diameter, 26 mm wide, giving 52 mm total stack width. Open on both faces, universally ground as a set. The ISO envelope is the 7216 medium series.
2MM — 15° contact angle in the Fafnir scheme; the MM prefix carries the P4S build216 — no leading 9, so this is the ISO 72 medium series, 80 mm bore: ISO equivalent 7216-CWI — super-precision spindle bearing seriesDU — duplex, ground as a matched setL — light preload
The 72 medium series has a heavier cross-section than the 70 light series at the same bore, so it carries more load for a given shaft diameter and runs at a lower speed ceiling. The 15° angle favours speed and radial stiffness over thrust, and light preload gives the coolest running of the three grades.

Matched duplex pair. 2 Pcs per sale unit.
Each bearing carries thrust in one direction; the pair mounted back-to-back or face-to-face covers both. The etched marks on the outer rings align to hold the matched offset as ground.
