Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 46T464322A Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 46T464322A, FAG 46T464322A, NSK 46T464322A. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Standard batches of CHG Bearing 46T464322A conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Beyond standard alloy steel, CHG Bearing can customize the 46T464322A Double Row Tapered 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.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 46T464322A 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.
