A Fafnir 3MM214WI-TUL super-precision angular contact ball bearing, single row, universally ground, from the WI machine-tool spindle series. Steel rings, steel balls, phenolic cage, open on both faces.
3MM — 25° contact angle.
214 — ISO 72 dimension series, bore code 14, giving a 70 mm bore. ISO equivalent 7214AC.
WI — Fafnir ground super-precision spindle series.
T — phenolic cage.
U — single universally ground.
L — light preload.
A 25° contact angle carries more thrust and less speed than a 15° ring of the same envelope, which suits a spindle whose axial cutting load dominates. Light preload keeps the running temperature and the frictional torque down at the cost of some axial stiffness. Universal grinding means the faces are flush-ground so any two rings of this designation seat together back-to-back, face-to-face or in tandem and arrive at the marked preload with no shims.
Bore: 70 mm (2.7559 in)
Outside diameter: 125 mm (4.9213 in)
Width: 24 mm (0.9449 in)
Contact angle: 25°
Precision class: ABEC 7 (P4S)
Preload: light
Cage: phenolic
Rolling elements: steel balls, single row
Closure: open both faces
3 Pcs, each a universally ground single. All three carry the same 3MM214WI-TUL designation.
ISO base number 7214, angle-designated 7214AC. Searchable forms are 3MM214WI-TUL, 3MM214WITUL and 3 MM 214 WI TUL. A 2MM214WI ring is the 15° version of the same envelope and is a related size, not an interchange; TUM and TUH are the medium and heavy preload grades and are likewise related sizes.
