A Fafnir M9223WI-3-102 super-precision angular contact ball bearing from the ground WI machine-tool spindle series. Steel rings and steel balls, open on both faces.
WI — Fafnir ground super-precision angular contact spindle series.
23 — bore code, giving a 115 mm bore.
-3-102 — factory deviation block, carried here as a cross-reference.
Angular contact geometry carries a radial load together with thrust in one direction, so these rings are ground for use in an opposed or matched arrangement. The 17.5 mm cross-section against a 14 mm width makes this a narrow high-speed section rather than a load-series bearing.
Bore: 115 mm (4.5276 in)
Outside diameter: 150 mm (5.9055 in)
Width: 14 mm (0.5512 in)
Rolling elements: steel balls, single row
Closure: open both faces
2 Pcs. Both rings carry the same designation.
The searchable forms of this number are M9223WI-3-102, M9223WI3102 and M 9223 WI 3 102. The carton also carries TJ437 L6. Same-envelope bearings with a different contact angle or preload grade are related sizes rather than interchanges.
