Fafnir 3MM211WI-TUL super precision angular contact ball bearing set from Timken. Series: 200WI. ISO equivalent: 7211. Bore: 55 mm. Outside Diameter: 100 mm. Width: 21 mm per bearing. Total Width: 63 mm. Timken world part number: 7211E-T-P4S-TUL.
Contact Angle: 25°. Precision Rating: ISO P4S, ABEC 7/9. Preload: light. Rows per set: triplex, three bearings. Cage: CR, machined phenolic, outer-ring-land-riding. Ball material: steel. Closure: open. Searchable forms include 3MM211WI-TUL, 3MM211WITUL, 3MM 211 WI TUL, 3MM-211-WI-CR-TUL, 7211E-T-P4S-TUL and 7211AC.
A 25° contact angle carries more thrust and less speed than a 15°, which suits spindles and screw drives where axial load dominates. Light preload keeps heat and running torque low while removing all play. A triplex set carries load on three rows, raising stiffness and capacity over a duplex pair in the same envelope. P4S tolerances hold tighter running accuracy and lower vibration than P4 alone.
Dynamic Radial Load Rating, triplex set: 55 900 N. Dynamic Radial Load Rating per row, ISO C1: 50 800 N. Static Radial Load Rating: 38 500 N. Limiting Speed, grease: 13 100 rpm. Limiting Speed, oil: 26 200 rpm.
Three bearings, supplied as a matched triplex set. Universally ground, so the set is matchable in triplex arrangements. Single row of balls per bearing.
Maximum shaft fillet radius: 1.5 mm. Shaft backing shoulder diameter: 63.3 mm. Housing backing shoulder diameter: 92.2 mm. Outer ring to-clear radius: 1.5 mm. Bore form is straight. Preload is ground into the faces, so no shim stack or clearance setting is required at assembly. Lubrication: oil or grease.
Closest match: FAG B7211-E-T-P4S-TUL. NSK 7211A5TRSULP4 is sold as single universally matchable bearings rather than a matched triplex set. Related size: SKF 7211 ACD/P4A, a single bearing without matched preload. A 7211 in a different contact angle, preload grade or piece count is a related size, not a direct substitute.
