A Fafnir 2M9110WI-DUL super-precision angular contact ball bearing, 50 mm bore by 80 mm outside diameter by 16 mm wide, with a phenolic cage, supplied as a matched duplex pair. Fafnir is Timken’s super-precision line.
The 2M prefix sets a 15° contact angle, which the 7010-C designation on the carton confirms independently. The leading 9 in 9110 places the bearing in the ISO 70 light dimension series, giving an ISO base number of 7010, and the 10 size code gives a 50 mm bore. WI marks the super-precision angular contact family, CR the phenolic outer-land-riding cage, and DUL a duplex set at light preload.
A 15° contact angle favours speed and radial stiffness over thrust capacity, the usual trade for machine tool spindle work. The ISO 70 light series keeps the outside diameter and section small for the bore, which lowers mass and raises attainable speed against a 72-series bearing of the same bore. The phenolic cage rides on the outer ring land and runs quiet and cool, with a lower temperature ceiling than steel or brass.
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 reaches light preload when clamped together without shims.
The pair is installed as a unit and not split between sets, since the ground offsets are matched within the pair. Mounting is onto a clean straight journal against a square shoulder, with the marked faces oriented to the chosen arrangement.
Same-envelope 15° precision equivalents include the SKF 7010 CD/P4ADGA and the FAG B7010-C-T-P4S-DUL. A 7010 at a 25° contact angle, in a different preload grade, or as a single rather than duplex grind is a related size and not an interchange.
