TIMKEN 2MM205WICRDUL SUPER PRECISION BEARING SET

Description:

The Timken 2MM205WICRDUL is a matched duplex set of super precision single-row angular contact ball bearings from the Timken Fafnir® 200WI series. Factory-matched with DUL (light preload), this bearing set is engineered for high-speed, high-precision spindle applications requiring exceptional rigidity, low runout, and accurate shaft positioning. It is widely used in CNC machining centers, milling machines, grinding machines, jig borers, and other precision machine tools.

Applications:

The Timken 2MM205WICRDUL bearing set is designed for machine tool spindles and other precision rotating equipment operating at high speeds. Its duplex configuration with light preload provides increased stiffness, improved rotational accuracy, and excellent thermal stability, making it ideal for CNC machining centers, high-speed milling machines, grinding equipment, precision lathes, routers, and similar industrial applications.
