A Fafnir 2MM9126WI-DUL super-precision angular contact ball bearing, 130 mm bore by 200 mm outside diameter by 33 mm wide, with a machined phenolic cage, supplied as a matched duplex pair. Fafnir is Timken’s super-precision line.
The 2MM prefix sets a 15° contact angle and carries P4S precision, equivalent to ABEC 7/9. The leading 9 in 9126 places the bearing in the ISO 70 light dimension series, giving an ISO base number of 7026, and the 26 size code gives a 130 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.
The dynamic load rating is 148 kN and the static rating 156 kN, at a limiting speed of 4300 rpm. A 15° contact angle trades thrust capacity for speed and radial stiffness, and light preload keeps frictional heat low so that limiting speed is usable rather than nominal. The phenolic cage runs quiet and cool on the outer ring land, and sets the service ceiling at 120 °C.
Two bearings, ground as a universal duplex set, open with no seals or snap rings. The rings are relieved so the pair mounts back-to-back, face-to-face or in tandem and reaches light preload when clamped without shims.
The pair is installed as a unit, since the ground offsets are matched within the set. Mounting is onto a clean straight journal against a square shoulder, with the marked faces oriented to the chosen arrangement. Service range is −30 to +120 °C.
The SKF 7026 CD/P4ADGA is a same-spec interchange at 15°, P4 class and duplex light preload. The NSK 7026CTYNSULP4 is an SU single-universal grind and the GMN S6026CTA a different family, so both are related sizes rather than substitutions.
