Fafnir 2MM9103WO-CR-DU-C4-E7236 super-precision angular contact ball bearing, supplied as a duplex pair. Bore Diameter: 17 mm. Outside Diameter: 35 mm. Overall Width: 10 mm per bearing. Series: 9100WO. Base Number: 9103. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing Steel. The 9103 size code matches the ISO 7003 envelope.
2MM — Contact Angle: 15°, in Timken’s MM super-precision spindle range.
MM — Precision Class: ABEC 7/9 (P4S), the tolerance grade the MM prefix carries.
9103 — the 17 mm bore size in the 9100 spindle series, on the ISO 7003 boundary dimensions.
CR — Cage Material: Phenolic.
DU — Mounting Arrangement: duplex, two bearings ground as a matched set.
C4 — Internal Clearance: C4, greater than normal.
E7236 — a Timken engineering suffix identifying the specific build of this order code.
Contact Angle: 15°. A 15° angle favours speed and radial stiffness, which is why it is the machine tool spindle standard. Internal Clearance: C4, a wider running fit that suits a tight shaft interference or a warm running housing. Precision Class: ABEC 7/9. Cage Material: Phenolic, light, self-lubricating and quiet at high surface speeds.
The straight bore seats directly on a ground spindle journal. Faces are universally ground so the two bearings of the set stack against each other and take up their built-in relationship when the clamp nut is tightened.
Unit Quantity: 2 Pcs. Number Of Rows: 2. A matched duplex set ships together.
The 17 x 35 x 10 mm envelope at 15° is the ISO 7003 C size, so a 15° super-precision 7003 duplex set from another maker fits the same seat. The Fafnir 2MM9103WI-CR-DU carries the same envelope with the WI low-shoulder ring form and is listed as a related execution.
