A single-row super-precision angular contact ball bearing in the Fafnir 200WI spindle series, 70 mm bore × 125 mm outside diameter × 24 mm width. The ISO equivalent designation is 7214 C.
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.
CR — phenolic cage riding on the outer ring land.
The MM prefix on a Fafnir spindle bearing carries P4S tolerances — ABEC 7 dimensional accuracy with ABEC 9 running accuracy.
A 15° contact angle biases the bearing toward speed and radial rigidity, and carries less thrust than a 25° bearing in the same envelope. Outer-land-riding phenolic cages are light, self-lubricating and dimensionally stable at high DN values, which is why they are standard on grinding and milling spindles. Phenolic places the working temperature ceiling near 120 °C. Rings and balls are through-hardened high-carbon chrome steel.
Bore: 70 mm (2.7559 in)
Outside diameter: 125 mm (4.9213 in)
Width: 24 mm (0.9449 in)
Contact angle: 15°
Precision class: ABEC 7 / ISO P4S
Dynamic load rating C: 75.4 kN
Static load rating C0: 63.5 kN
Limiting speed: 12,000 rpm
Rows: 1
Cage: phenolic, outer-land-riding
Rolling elements: steel balls
Bearing material: high-carbon chrome steel
Closure: open, both faces
ISO equivalent: 7214 C
Single bearing, 1 Pc. The universally ground faces allow assembly into a duplex or triplex stack of matching bearings, where the arrangement sets the preload.
Mounting is an interference fit on the shaft and a close fit in the housing bore, both held to super-precision spindle limits. Faces seat against square ground shoulders, and a runout error at the shoulder transfers directly into the raceway.
15° P4-class bearings of this size: SKF 7214 CD/P4A, FAG B7214-C-T-P4S and NSK 7214CTR. The Fafnir 3MM214WI is the same size at a 25° contact angle.
