Product Description

What this part is

Fafnir 3MM9115WI-DUL matched duplex pair of super-precision angular contact spindle ball bearings, built by The Timken Company. Series: 9100WI. Bore: 75 mm. Outside Diameter: 115 mm. Bearing Width: 20 mm per bearing. Total Width: 40 mm for the pair. Contact Angle: 25°. Precision Rating: ISO P4S (ABEC 7/9). Preload: Light. Cage Type: CR – Phenolic Outer Land Riding Cage. Cage Material: Phenolic. Rolling Elements: steel balls. Bearing Material: high carbon chrome steel. Bore Type: Straight. Closure Type: Open. Rows per Set: Duplex. Design Units: Metric. Timken’s world part number for this set is 7015E-T-P4S-DUL.

Decoding the designation

The 3MM prefix gives a 25° contact angle and ISO P4S accuracy. 9115 in the 9100WI series is the ISO 7015 envelope. WI denotes a low shoulder on both rings. CR is the phenolic outer-land-riding cage. DU marks a duplex set, and the trailing L sets light preload.

What these specs mean in practice

Dynamic Radial Load Rating (C1): 48,900 N (11,000 lbf) per bearing. C1 ISO Dynamic Radial Rating per row: 44,400 N (10,000 lbf). Static Radial Load Rating (C0): 41,200 N (9,260 lbf) per bearing. Limiting Speed – Grease: 11,000 rpm. Limiting Speed – Oil: 19,800 rpm. Lubricant: grease or oil. A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Light preload adds the least heat of the three grades.

Quantity and configuration

Unit Quantity: 2 Pcs. Arrangement / Configuration: Matched duplex pair. Total Width: 40 mm assembled. The two bearings are ground as a set and mount together at the published light preload.

Mounting data

Max Shaft Fillet Radius: 1 mm (0.039 in). Outer Ring To Clear Radius: 1 mm (0.039 in). Shaft Backing Shoulder Diameter: 82.7 mm (3.260 in). Housing Backing Shoulder Diameter: 107.3 mm (4.230 in).
