Timken 2MM210WI Super Precision Angular Contact Ball Bearing

The Timken 2MM210WI is a super precision single-row angular contact ball bearing from Timken Fafnir's 200WI series, engineered for high-speed, high-accuracy machine tool spindles. It features a 50 mm bore, 90 mm outside diameter, and 20 mm width with a 15° contact angle and ISO P4S (ABEC 7/9 equivalent) precision, housed in a CR outer land riding cage and phenolic (MBR) cage material. Dynamic radial load rating is 47.4 kN (10,700 lbf) and static radial load rating is 31.7 kN (7,130 lbf), with a per-row ISO dynamic rating of 43.1 kN (9,730 lbf); limiting speeds are 16,000 rpm in grease and 32,000 rpm in oil. Designed to support combined radial and axial loads, it delivers low runout, high rigidity, and reliable performance for CNC machining centers, vertical milling machines, jig borers, high-speed routers, grinding equipment, and other precision spindle applications.
