2MM9109WIDUL Angular Contact Ball Bearing Super Precision P4S DUL

The 2MM9109WI DUL is a super-precision angular contact ball bearing set from Timken's Fafnir MM series. This duplex universal set includes two flush-ground bearings with a 15° contact angle, 45mm bore, and maximum-capacity WI internal design for low to moderate speed applications. The set may be mounted back-to-back, face-to-face, or tandem depending on load requirements.

Manufactured to Timken P4S precision (ABEC 7 dimensional tolerances with ABEC 9 running accuracy), this bearing is designed for machine tool spindles, precision gearboxes, and other applications requiring high rotational accuracy and rigidity. The light preload and open design make it suitable for applications where external sealing is provided and precision positioning is critical.
