FCD6492340p5 460 mm 320 mm 360 mm 340 mm Frequently Asked Questions about FCD6492340p5 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies FCD6492340p5 with a precision bore diameter (d) of 320 mm, an outside diameter (D) of 460 mm, and a nominal ring width (B) of 340 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
Each FCD6492340p5 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (320 mm bore side) ensures perfect planar contact without edge binding.
Built for demanding industrial environments, the FCD6492340p5 Four-Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing FCD6492340p5 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
