Fafnir 2MM9102WI-DUL super-precision angular contact ball bearing, supplied as a universally ground duplex pair. Series: 9100WI. Base Number: 2MM9102WI. Bore Diameter: 15 mm. Outside Diameter: 32 mm. Overall Width: 9 mm per bearing. Total Width: 18 mm for the pair. Bore Type: Straight. Closure Type: Open. Rolling Elements: Ball. Number Of Rows: 1 per bearing. Bearing Material: Chrome steel. Item Weight: 0.060 kg (0.14 lb) per bearing.
2MM — 15° contact angle in the Fafnir super-precision spindle range.
MM — super-precision spindle execution, ISO P4S tolerance, ABEC 7/9.
9100 — the ISO 70xx light dimension series; 9102 is the ISO 7002 envelope.
WI — low shoulder on both rings, giving the ball set a clear assembly path and a defined thrust face.
CR — phenolic outer-ring land-riding cage.
DUL — duplex pair, universally ground, light preload.
Contact Angle: 15°. A 15° angle favours speed and radial stiffness over thrust capacity, which is why it is the standard choice for grinding and milling spindles.
Dynamic Load Rating: 7,300 N. Static Load Rating: 3,600 N. Both figures are per bearing.
Limiting Speed: 48,800 rpm grease; 97,200 rpm oil. Lubricant: grease or oil.
Precision Class: ABEC 7/9 / P4S. Cage Material: Phenolic. Cage Type: Outer-ring land riding. A phenolic cage riding on the outer ring land runs quiet at speed and carries lubricant in the cage pockets.
Preload: Light. Internal Clearance: N/A — a preloaded set is elastically loaded rather than clearance-set.
Maximum Housing Fillet Radius: 0.3 mm. Shaft Backing Shoulder Diameter: 18.9 mm. Housing Backing Shoulder Diameter: 28.6 mm. These are the abutment figures the bearing corners will clear.
Unit Quantity: 2 Pcs. Mounting Arrangement: universally ground duplex. Universal grinding lets the two rings be set back to back, face to face or in tandem and still produce the published light preload when clamped.
GTIN: 087796077720. The interchanges below share the 15 x 32 x 9 mm envelope at a 15° contact angle in a P4-class light-preload universally matchable pair. Where a candidate part differs in contact angle or preload class it is a related size rather than a drop-in substitution.
