Fafnir 3MM9109WI-DUL matched duplex pair of super-precision angular contact ball bearings, ISO 70-series light section. Brand: Fafnir (Timken). Part Number: 3MM9109WI-DUL. Bore: 45 mm. Outside Diameter: 75 mm. Overall Width: 16 mm per bearing. Design Units: Metric. Number Of Rows: 1 per bearing. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: High carbon chrome bearing steel. Item Weight: 0.53 lbs.
Contact Angle: 25°. Precision Class: P4S. Precision Rating: ABEC 7/9. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Preload: Light. Arrangement / Configuration: Matched duplex pair, universally ground. Series: 9100, Fafnir’s designation for the ISO 70xx light series — a 9109 carries the 7009 envelope.
A 25° contact angle carries more thrust load and locates the shaft more stiffly along its axis than a 15° bearing on the same envelope. Dynamic Load Rating: 25.6 kN / 5755 lbf. Static Load Rating: 18.3 kN / 4114 lbf. Limiting Speed: 32200 rpm. The machined phenolic cage rides on the outer ring land, staying centred at spindle speeds and holding lubricant against the ball pockets. Internal Clearance: N/A — the pair is set by preload rather than by clearance.
Unit Quantity: 2 Pcs. Mounting Arrangement: Universal. The two bearings are ground as a matched set, so mounting them against one another produces the light preload class directly, with no shims and no regrinding. Universal grinding also lets the pair be set back-to-back, face-to-face or in tandem. Total Width: 32 mm for the pair as mounted.
Cross-References: SKF 7009 ACD/P4A DGB, FAG B7009-E-T-P4S-DUL, NSK 7009A5TRDULP4. Each is a 25° light-preload duplex set on the 45 x 75 x 16 mm envelope. Harmonization Code: 8482.10.50.
