A single-row super-precision angular contact ball bearing in the Fafnir 200WI spindle series. Brand: Fafnir (Timken). Part Number: 2MM214WI-SUH. Bore: 70 mm (2.7559 in). Outside Diameter: 125 mm (4.9213 in). Overall Width: 24 mm (0.9449 in). ISO Equivalent: 7214 C. GTIN: 087796070851.
2MM — 15° contact angle, Fafnir super-precision spindle bearing. 214 — 200 dimension series, bore code 14, giving a 70 mm bore. WI — spindle angular contact ball bearing, universally ground faces. SU — single bearing, universally ground for matching. H — heavy preload.
The MM prefix on a Fafnir spindle bearing carries P4S tolerances — ABEC 7 dimensional accuracy with ABEC 9 running accuracy.
Contact Angle: 15°. Precision Class: ABEC 7 / ISO P4S. Preload: Heavy (H). Number Of Rows: 1. Cage Material: Phenolic, outer-land-riding. Rolling Elements: Steel balls. Closure Type: Open, both faces. Bore Type: Straight. Arrangement / Configuration: SU — single, universally ground. Unit Quantity: 1 Pc.
A 15° contact angle biases the bearing toward speed and radial rigidity, and carries less thrust than a 25° bearing in the same envelope. Heavy preload raises axial and radial stiffness and holds the ball complement in a fixed contact path under load reversal, at the cost of extra running friction and heat, so it belongs on rigid, well-cooled spindles rather than long unsupported shafts.
Single bearing, 1 Pc. Universal grinding allows it to be stacked back-to-back, face-to-face or in tandem with matching bearings of the same designation.
Same-spec 15° P4 equivalents in other schemes are the SKF 7214 CD/P4A, FAG B7214-C-T-P4S and NSK 7214CTR, matched for heavy preload. The 3MM214WI is a 25° bearing in the same envelope, and the SUL and SUM variants differ in preload — those are related sizes rather than interchanges.
