Timken 2MM9119WI DUL Angular Contact Ball Bearing

The Timken 2MM9119WI DUL is a factory-matched duplex set of super-precision single-row angular contact ball bearings from the Timken Fafnir 9100WI series, configured with light preload (DUL) for high-speed machine tool spindles that demand rigidity and low runout. The pair has a 95 mm bore, 145 mm outside diameter, and 24 mm per-bearing width (48 mm total for the duplex), a 15° contact angle, and ISO P4S precision with steel balls in a CR outer land riding cage and a MBR phenolic cage, arranged as a duplex matched pair to improve spindle stiffness and thermal stability. World Part Number 7019C-T-P4S-DUL (MPN 2MM9119WICRDUL) identifies this unit in Timken Fafnir's 9100WI family; dynamic radial load ratings are 81,400 N per bearing (C1) and 74,100 N per bearing (ISO dynamic), static radial load rating 73,400 N per bearing, and limiting speeds of 8,700 rpm with grease or 17,400 rpm with oil, with maximum shaft and housing fillet radii of 1.5 mm. This bearing set supports combined radial and axial loads in high-speed precision spindle applications, making it suitable for CNC machining centers, grinding machines, high-speed milling machines, machining spindles, routers, and other precision machine tools.
