2MM203WIDUL Superprecision Duplex Angular Contact Ball Bearing

The 2MM203WIDUL is a super-precision duplex angular contact ball bearing from Timken's Fafnir MM series. This matched set of two bearings features a 17mm bore, 40mm outside diameter, and 15° contact angle with maximum-capacity WI internal design. The duplex universal arrangement allows flexible mounting in back-to-back, face-to-face, or tandem configurations with light preload.

Precision ground to Timken P4S class (ABEC 7 dimensional tolerances with ABEC 9 running accuracy), this bearing is designed for machine tool spindles, precision grinding equipment, and other applications requiring high rotational accuracy at low to moderate speeds. The open design without seals provides minimal friction and easy lubrication access.
