Fafnir 3MM9116WI super-precision angular contact ball bearing, 9100 series. Brand: Fafnir (Timken). Part Number: 3MM9116WI. Bore: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. Total Width: 22 mm. Design Units: Metric. Number Of Rows: 1. Rolling Elements: Steel ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome bearing steel. Item Weight: 3.90 lbs.
Contact Angle: 25°. Precision Class: P4S. Precision Rating: ABEC 7/9. Cage Material: Phenolic. Cage Type: CR – phenolic outer land riding. Series: 9100, Fafnir’s designation for the ISO 70xx series — a 9116 carries the 7016 envelope. Timken World Part Number: 7016E-T-P4S.
Dynamic Radial Load Rating (C1), per bearing: 61,400 N (13,800 lbf). Dynamic Radial Load Rating (C1 ISO, per row): 56,000 N (12,500 lbf). Static Radial Load Rating (C0), per bearing: 52,500 N (11,800 lbf). Limiting Speed, grease: 10,200 rpm. Limiting Speed, oil: 18,600 rpm.
A 25° contact angle carries more thrust load and holds the shaft more stiffly along its axis than a 15° bearing on the same envelope. The 70-series section fits an 80 mm shaft inside a 125 mm housing bore. The phenolic cage rides on the outer ring land, staying centred at speed and holding lubricant against the ball pockets. Oil feed lifts the speed ceiling from 10,200 to 18,600 rpm.
Shaft Backing Shoulder Diameter: 88.5 mm (3.490 in). Housing Backing Shoulder Diameter: 116.5 mm (4.590 in). Maximum Shaft Fillet Radius: 1 mm (0.039 in). Outer Ring “To Clear” Radius: 1 mm (0.039 in).
Unit Quantity: 1 Pc. Mounting Arrangement: Universal.
