Fafnir 3MM207WI-TBL super precision angular contact ball bearing set from Timken. Series: 200WI. ISO equivalent: 7207. Bore: 35 mm. Outside Diameter: 72 mm. Width: 17 mm per bearing. Total Width: 51 mm. Timken world part number series: 7207E-T-P4S.
Contact Angle: 25°. 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 3MM207WI-TBL, 3MM207WITBL, 3MM 207 WI TBL, 3MM-207-WI-TBL, 7207-E, 7207-A, 7207A5 and 7207ACD.
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 generation and running torque low while removing all play. Three rows in one envelope raise stiffness and capacity over a duplex pair. P4S tolerances hold tighter running accuracy and lower vibration than P4 alone.
Dynamic Radial Load Rating, triplex set: 32 200 N. Dynamic Radial Load Rating per row, ISO C1: 29 300 N. Static Radial Load Rating: 19 100 N. Limiting Speed, grease: 21 200 rpm. Limiting Speed, oil: 38 800 rpm.
Three bearings, supplied as a matched triplex set. Single row of balls per bearing. Total stack height 51 mm.
Maximum shaft fillet radius: 1 mm. Shaft backing shoulder diameter: 42.2 mm. Housing backing shoulder diameter: 65.3 mm. Outer ring to-clear radius: 1 mm. Bore form is straight. Preload is ground into the faces, so no shim stack or clearance setting is required at assembly. Lubrication: oil.
Same-specification equivalents: FAG B7207-E-T-P4S in a light-preload triplex execution, SKF 7207 CE/P4A. A 7207 in a different contact angle, preload grade or piece count is a related size, not an interchange.
