The 2MM9108WI DUL is a super-precision angular contact ball bearing supplied as a duplex universal matched set of two bearings. This open design bearing features a 40 mm bore, 68 mm outside diameter, 15° contact angle, and maximum-capacity WI internal geometry optimized for low to moderate speed applications. The set is precision ground for flush mounting in back-to-back (DB), face-to-face (DF), or tandem (DT) arrangements with light preload.
Super-precision angular contact ball bearings are used in machine tool spindles, precision motors, pumps, and other applications requiring high accuracy and rigidity. The P4S precision class delivers dimensional tolerances to ABEC 7 (ISO P4) with running accuracy meeting ABEC 9 (ISO P2), making it suitable for demanding precision machinery where tight radial and axial runout control is critical.
