TIMKEN 2MM210WI PRECISION BEARING

Description:

The Timken 2MM210WI precision bearing is a super precision single-row angular contact ball bearing from the Timken Fafnir® 200WI series. Designed for high-speed, high-accuracy machine tool spindles, it supports combined radial and axial loads while delivering exceptional rigidity, precision, and running accuracy. It is widely used in CNC machining centers, milling machines, grinding machines, jig borers, routers, and other precision manufacturing equipment where tight tolerances and high rotational speeds are essential.

Applications:

The Timken 2MM210WI precision bearing is engineered for high-speed spindle applications requiring outstanding accuracy, stiffness, and reliability. Its 15° contact angle and P4S (ABEC 7/9 equivalent) precision rating make it ideal for precision machine tool spindles, CNC machining centers, vertical milling machines, jig boring machines, high-speed routers, grinding equipment, and other industrial applications requiring low runout and excellent thermal stability.
