A matched duplex pair of Fafnir 3MM9106WI super precision angular contact ball bearings, universally ground for heavy preload (DUH). Each bearing is 30 mm bore x 55 mm OD x 13 mm wide, so the pair stacks to 26 mm overall. The 9100WI line is Fafnir’s light-section spindle series on the 7006 envelope.
3MM — Fafnir super precision series, 25° contact angle, ABEC 7 / P4 precision.
9106 — 9100 light-section series, 7006 envelope, 30 x 55 x 13 mm.
WI — super precision spindle bearing design.
DUH — duplex, universally ground, heavy preload.
Bearing Type: Super precision angular contact ball bearing. Bore Diameter: 30 mm. Outside Diameter: 55 mm. Width: 13 mm each bearing. Total Width Mounted As A Pair: 26 mm. Contact Angle: 25°. Precision Class: ABEC 7 / P4. Preload: Heavy (H). Number Of Rows: 1 per bearing, duplex pair. Closure Type: Open. Bore Type: Straight. Rolling Elements: Ball. Series: 3MM 9100WI. Unit Quantity: 2 Pcs. Harmonization Code: 8482.10.50.68.
