A duplex matched pair of Fafnir super precision angular contact ball bearings, part number MM9310WI-2H DU, designed for high-speed spindle and ball screw support applications requiring precise axial and radial load handling. The MM9310WI-2H DU designation indicates a matched duplex set with high preload (2H) and low shoulder outer ring (WI), configured for face-to-face or back-to-back mounting depending on application requirements.

Each bearing in the pair measures 38.1 mm (1.500 in.) bore diameter, 72 mm (2.835 in.) outer diameter, and 15.875 mm (0.625 in.) width, with overall duplex set width of 31.75 mm (1.250 in.). Precision grade is ABEC-7 (ISO P4), consistent with the Fafnir MM9-H super precision series designation. Contact angle designation corresponds to the 2MM prefix series used in this product family. Both bearings are open type with steel ball complement.
