Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing NNU4080/P5 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 Double Row Cylindrical Roller Bearings.
Beyond standard alloy steel, CHG Bearing can customize the NNU4080/P5 Double Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Each NNU4080/P5 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.
To match diverse operational dynamics, CHG Bearing supplies NNU4080/P5 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
