A Fafnir 2MM222WI-DUL super-precision angular contact ball bearing, 110 mm bore by 200 mm outside diameter by 38 mm wide, supplied as a factory-matched duplex pair. Fafnir is Timken’s super-precision line and the two brands share the 087796 UPC prefix.
The 2MM prefix sets a 15° contact angle, and the MM prefix carries P4S precision, equivalent to ABEC 7/9. The absence of a leading 9 places the bearing in the ISO 72 dimension series, giving an ISO base number of 7222. The 222 size code corresponds to a 110 mm bore. WI marks the super-precision angular contact family and DUL denotes a duplex set at light preload.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why it is the usual choice for machine tool spindles rather than heavy axial duty. Light preload holds the balls in defined contact for running accuracy while keeping frictional heat low, so the pair tolerates higher shaft speeds than a medium or heavy preload of the same size would.
Two bearings, ground as a universal duplex set. The rings are relieved so the pair mounts back-to-back, face-to-face or in tandem, and the preload comes up correctly when the two are clamped together without shims.
The same-spec equivalents at 15° and P4-class precision with duplex light preload are the SKF 7222 CD/P4ADGA, the FAG B7222-C-T-P4S-DUL and the NSK 7222CTRDULP4. A 7222 in a 25° angle, a different preload grade or a single rather than duplex grind is a related size, not an interchange.
