2MM212WIDUL Superprecision Duplex Angular Contact Ball Bearing

The 2MM212WIDUL is a super-precision duplex angular contact ball bearing with 60mm bore, 110mm outside diameter, and 44mm combined width. This Timken/Fafnir MM series bearing features a 15° contact angle, maximum-capacity WI internal design, light preload, and P4S precision class (ABEC 7 tolerances with ABEC 9 running accuracy). The duplex universal arrangement allows mounting in back-to-back, face-to-face, or tandem configurations.

Super-precision angular contact ball bearings are designed for applications requiring high rotational accuracy and rigid shaft support under combined radial and axial loads. Typical applications include machine tool spindles, precision gearboxes, and high-accuracy rotating equipment in industrial machinery where precise positioning and minimal runout are critical.
