TIMKEN 2MM205WI DUL 7205C-T-P4S SUPER PRECISION BALL BEARING SET 2MM205WICRDUL

Description:

The Timken 2MM205WICRDUL (Manufacturing Part Number: 2MM205WI DUL, World Part Number: 7205C-T-P4S-DUL) 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 designed for high-speed machine tool spindles requiring exceptional rigidity, low runout, and precise shaft positioning. It is commonly used in CNC machining centers, milling machines, grinding machines, jig borers, routers, and other precision manufacturing equipment.

Applications:

The Timken 2MM205WICRDUL bearing set is engineered for high-speed spindle applications where accuracy, rigidity, and thermal stability are critical. The duplex light preload arrangement improves spindle stiffness, minimizes vibration, and provides excellent rotational accuracy, making it suitable for CNC machining centers, high-speed milling machines, precision lathes, grinding machines, machining spindles, and other industrial machine tools.
