A Fafnir 3MMV9115WI-CR-DUL super-precision angular contact ball bearing set, two rings ground as a matched duplex pair. Steel rings, steel balls, phenolic cage, open on both faces.
3MM — 25° contact angle.
9115 — leading 9 marks the ISO 70 light series; bore code 15 gives a 75 mm bore. ISO equivalent 7015AC.
WI — Fafnir ground super-precision spindle series.
CR — phenolic outer-land-riding cage.
DUL — duplex, universally ground, light preload.
A 25° contact angle carries more thrust and less speed than a 15° ring on the same 75 x 115 x 20 mm envelope. An outer-land-riding phenolic cage is guided by the outer ring rather than by the balls, which cuts cage wear and slinging at high speed and keeps the assembly light. Light preload trades axial stiffness for a lower running temperature. The rings are flush-ground as a pair, so they seat back-to-back, face-to-face or in tandem and reach the marked preload with no shim stack.
Bore: 75 mm (2.9528 in)
Outside diameter: 115 mm (4.5276 in)
Width per ring: 20 mm (0.7874 in)
Total width of the pair: 40 mm (1.5748 in)
Contact angle: 25°
Precision class: ABEC 7 (P4S)
Preload: light
Cage: phenolic, outer-land-riding
Rolling elements: steel balls, single row per ring
Closure: open both faces
2 Pcs, supplied as one matched duplex pair.
ISO base number 7015, angle-designated 7015AC. Searchable forms are 3MMV9115WI-DUL, 3MMV9115WIDUL, 3MMV9115WI-CR-DUL and 3MMV 9115 WI CR DUL. A 2MMV9115WI ring is the 15° version of the same envelope and is a related size, not an interchange; DUM and DUH are the medium and heavy preload grades, and SU singles are a different arrangement, so all three are related sizes.
