Fafnir 2MM215WI-TUL super precision angular contact ball bearing set from Timken. Series: 200WI. ISO equivalent: 7215. Bore: 75 mm. Outside Diameter: 130 mm. Width: 25 mm per bearing. Total Width: 75 mm. Timken world part number: 7215C-T-P4S-TUL.
Contact Angle: 15°. Precision Rating: ISO P4S, ABEC 7/9. Preload: light. Rows per set: triplex, three bearings. Cage: machined phenolic, outer-ring-land-riding. Ball material: steel. Closure: open. Searchable forms include 2MM215WI-TUL, 2MM215WITUL, 2MM 215 WI TUL, 2MM-215-WI-CR-T/TRI and 7215C-T-P4S-TUL.
A 15° contact angle favours speed and radial rigidity, which suits high-speed machine tool spindles. Light preload keeps heat generation and running torque low while still removing all play. A triplex set spreads load across 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: 87 900 N. Dynamic Radial Load Rating per row, ISO C1: 79 900 N. Static Radial Load Rating: 64 900 N. Limiting Speed, grease: 10 800 rpm. Limiting Speed, oil: 21 600 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: 85.2 mm. Housing backing shoulder diameter: 120.8 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.
Same-specification equivalent: FAG B7215-C-T-P4S-TUL. A 7215 in a different contact angle, preload grade or piece count is a related size, not an interchange.
