IBC 71906ETP4UL single-row super-precision angular contact ball bearing. Bore: 30 mm. Outside diameter: 47 mm. Width: 9 mm. Series: 719, ultra-light section. Bore form: straight. Closure: open on both faces. Rolling elements: bearing steel balls in a machined phenolic cage riding on the outer-ring land.
Contact Angle: 25°, from the E. Cage Material: T, fabric-base laminate phenolic. Precision Class: P4, equivalent to ABEC 7. Preload: UL, universal light — the bearing is flush-ground so pieces stack in any combination and reach light preload without shims. The carton also carries the cross-referenced number 3MV9306WICRSUL and the plain form 7906, and the Q155 execution code, all held as searchable part-number variants.
Dynamic Load Rating: 8.5 kN. Static Load Rating: 4.35 kN. Limiting Speed: 30,000 rpm. A 25° contact angle carries roughly twice the thrust of a 15° bearing on the same envelope and gives higher axial stiffness. The 719 ultra-light section keeps the cross-section thin, which is what allows a 30 mm bore in a 47 mm housing bore. A phenolic cage riding on the outer-ring land is light and damps cage motion, which is what supports the 30,000 rpm figure. Operating range: -30 °C to 120 °C.
Unit Quantity: 1 Pc. One universally flush-ground bearing, individually packaged, supplied open. Item weight: 0.11 lb.
Straight bore, mounted directly on the shaft seat. Faces are flush-ground for back-to-back, face-to-face or tandem stacking against further UL pieces. Internal Clearance: N/A on a preloaded execution.
FAG B71906-E-T-P4S matches on angle, cage material and precision class. SKF 71906 ACE/P4A is the equivalent 25° execution on the same 30 x 47 x 9 mm envelope. SKF 71906 CE/P4A shares the envelope at 15° and is a related size.
