Fafnir 3MM9117WI-SUL super precision single-row angular contact ball bearing. Bore: 85 mm (3.3465 in). Outside Diameter: 130 mm (5.1181 in). Overall Width: 22 mm (0.8661 in). ISO 7017 envelope, open on both faces, with a phenolic outer-land-riding cage.
Contact Angle: 25°. Precision Class: P4S (ABEC 7/9). Series: Fafnir 9100WI, the ISO 70 light dimension family, bore code 17 giving an 85 mm bore. Cage Material: Phenolic. Cage Type: Outer-land-riding, from the CR carton marking. Arrangement: single, universally ground. Preload: Light. Searchable forms of the number: 3MM9117WI-SUL, 3MM-9117-WI-SUL, 3MM9117WISUL, 3MM9117WI-CR-SUL, 3MM 9117 WI SUL.
A 25° contact angle carries more thrust and less speed than a 15° bearing of the same envelope, which makes it the usual choice where axial stiffness governs. The 70 light section keeps the outside diameter modest for the bore, which suits a compact spindle nose. Light preload holds running torque and heat generation down. A single row takes thrust in one direction.
Dynamic Load Rating: 63.0 kN (63,000 N / 14,000 lbf). Static Load Rating: 48.0 kN (48,000 N / 10,800 lbf). Item Weight: 2.13 lb (0.996 kg). Maximum shaft or housing fillet radius cleared by the bearing corner: 1.0 mm (0.039 in).
Bearing Material: chrome bearing steel. Rolling Elements: steel balls, single row. Number of Rows: 1. Bore Type: Straight. Closure Type: Open both faces. Internal Clearance: N/A — the SUL execution is preload-set. Lubricant: grease or oil.
Unit Quantity: 1 Pc. Single bearing, universally ground, so it mounts alone or stacks back-to-back, face-to-face or in tandem, with preload established by the ground faces.
ISO designation: 7017E-T-P4S at 25°. Cross-Reference 1: FAG B7017-E-T-P4S-UL (25°, universal, light preload). A 2MM9117WI shares the 85 x 130 x 22 mm envelope at a 15° contact angle and is a related part, as are the medium and heavy preload variants.
Machine tool spindles, grinding spindles, precision gearboxes and high-speed rotating assemblies. Harmonization Code: 8482.10.50. Country of Origin: United States.
