GTIN: 087796068391. Unit Quantity: 1 Pc. Decoding the designation: 7216: 80 mm bore, ISO 72 medium section, angular contact. WN: 40° contact angle in Fafnir’s lettering system. SU: a single bearing, universally ground, so any two will pair back-to-back, face-to-face or in tandem without shims. Searchable variants: 7216WNSU, 7216WN SU, 7216WN-SU, 7216 WN SU. What these specs mean in practice: A 40° contact angle is the steepest in the standard angular contact range: it carries the highest thrust load of any single-row execution on this envelope, and it trades speed for that capacity. Universal grinding means the faces are held to a common width so a second bearing of the same designation mounts against it and sets its own preload. ABEC 3 / P6 tolerances are the standard commercial range. Operating temperature range: -30 °C to 120 °C. Quantity and configuration: Unit Quantity: 1 Pc. One single bearing, universally ground, open on both faces. Fitting notes: Straight bore, so the inner ring seats on a cylindrical shaft journal. A 40° bearing takes thrust in one direction only, and the high shoulder sits on the side that carries it. Interchange guidance: Same envelope and same 40° angle: SKF 7216 BEP and MRC 7216DU. A 7216 in a 15° or 25° execution shares the envelope but not the thrust capacity, which makes it a related size rather than a substitute.
