Fafnir 2MM209WI-DUL, a super-precision angular contact ball bearing built by Timken under the Fafnir brand and supplied as a universally ground duplex pair. Bore Diameter: 45 mm. Outside Diameter: 85 mm. Overall Width: 19 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4S. Cage Type: CR — phenolic outer land riding cage. Cage Material: Phenolic. Rolling Elements: Ball. Bearing Material: Chrome steel. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1 per bearing. Preload: Light.
2MM — 15° contact angle on the Fafnir super-precision range, with the MM prefix carrying ISO P4S tolerancing.
209 — the 200WI medium series, which maps to the ISO 72xx family; this size is the ISO 7209.
WI — low shoulder on both rings, the high-speed spindle execution.
CR — phenolic outer land riding cage, guided on the outer ring land.
DU — duplex, two bearings ground for matched mounting as a set.
L — light preload. Timken’s world part number for this execution is 7209C-T-P4S-DUL.
Dynamic Load Rating: 45,200 N per bearing. Static Load Rating: 28,800 N per bearing. Limiting Speed: 17,500 rpm grease; 35,000 rpm oil. The 200WI medium series carries a heavier section than the 9100WI light series on the same 45 mm bore, which is where the higher load ratings come from. The 15° contact angle favours speed and radial stiffness; a 25° execution trades speed away for axial load. Internal Clearance: N/A — a preloaded set is axially preloaded rather than clearance-set. Lubricant: grease or oil.
Shaft backing shoulder diameter: 52.3 mm (2.060 in). Housing backing shoulder diameter: 78.2 mm (3.080 in). Total width of the mounted pair: 38 mm. Series: 200WI. Base Number: 2MM209WI.
Unit Quantity: 2 Pcs. Mounting Arrangement: Duplex. The two bearings are universally ground, so the pair can be set back-to-back, face-to-face or in tandem and will carry the light preload built into the grind.
Direct metric super-precision equivalents at 15° and P4 class: SKF 7209 CD/P4ADGA, FAG B7209-C-T-P4S-DUL, NSK 7209CTYNDULP4, NTN 7209UCDB/GNP4, RHP 7209CTDULP4, Koyo 7209C DB/GLP4, SNR 7209CVDUJ74.
