The 2MM218WI DUL is a super-precision angular contact ball bearing set from Timken's Fafnir MM series. This duplex universal arrangement consists of two flush-ground bearings with 15° contact angle, 90mm bore, and maximum-capacity WI internal design optimized for low to moderate speed applications. The set meets P4S precision class with ABEC 7 dimensional tolerances and ABEC 9 running accuracy, featuring light preload and open construction.
Duplex universal sets provide flexibility in mounting configurations—back-to-back for maximum rigidity, face-to-face for moment load capacity, or tandem for increased radial load capability. Common applications include machine tool spindles, precision gearboxes, and high-accuracy rotary tables where controlled preload and superior running accuracy are essential.
