Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing FC3448180 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Four-Row Cylindrical Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies FC3448180 with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 240 mm, and a nominal ring width (B) of 180 mm. This configuration yields an effective cross-sectional wall thickness of 35.0 mm and an envelope ratio (D/d) of 1.41, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects FC3448180 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
The Open Type engineered for FC3448180 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
