Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NNCF4980V Full Complement Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NNCF4980V, FAG NNCF4980V, NSK NNCF4980V. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each NNCF4980V 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 (400 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies NNCF4980V with a precision bore diameter (d) of 400 mm, an outside diameter (D) of 540 mm, and a nominal ring width (B) of 140 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.35, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the NNCF4980V Full Complement 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.
