Fafnir 2MM9106WO-CR-DU super-precision angular contact ball bearing, 9100WI spindle range, 30 x 55 x 13 mm. Bore Diameter: 30 mm. Outside Diameter: 55 mm. Overall Width: 13 mm. Contact Angle: 15°. Precision Class: ABEC 7/9 / P4S. Cage Material: Phenolic. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome steel. Number Of Rows: 2. Mounting Arrangement: Universal. Lubricant: grease or oil. Series: 9100WI. Base Number: 2MM9106WO.
2MM — 15° contact angle.
MM — Fafnir super-precision execution, ISO Class P4S, equivalent to ABEC 7/9.
9106 — 9100 spindle series, 30 mm bore.
CR — phenolic cage.
DU — duplex set of two universally ground bearings.
A 15° contact angle biases the bearing toward speed and radial stiffness, carrying less thrust than a 25° execution and running cooler at high spindle rpm.
Precision Class: ABEC 7/9 / P4S. Tighter bore, outside diameter and raceway tolerances hold the shaft on centre and lower running vibration, which is what machine tool spindles are bought for.
Cage Material: Phenolic. A machined phenolic cage is light, damps vibration and holds oil in its own structure, which suits sustained high-speed running.
Bearing Material: Chrome steel. Rolling Elements: Ball. Closure Type: Open, so the bearing takes lubricant directly from the spindle system. Lubricant: grease or oil.
Bore Type: Straight, for a plain cylindrical shaft seat. Mounting Arrangement: Universal — universally ground faces allow the pair to be set back-to-back, face-to-face or in tandem.
The bearing is preload-set as a matched pair rather than clearance-set.
Unit Quantity: 2 Pcs. One duplex set of two universally ground bearings, supplied together as the sale unit.

Cross-Reference 5: 2MM9106WI-CR-DUL is the WI-shoulder execution on the same 30 x 55 x 13 mm envelope and is a related part rather than a direct interchange.
Searchable forms of the designation: 2MM9106WOCRDU, 2MM9106WO-CR-DU, 2MM-9106-WO-CR-DU, 2MM9106WOCRDUC6.
