Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 777/431XTM 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 Tapered Roller Bearings.
As standard production, CHG Bearing subjects 777/431XTM 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 777/431XTM with a precision bore diameter (d) of 431.8 mm, an outside diameter (D) of 571.5 mm, and a nominal ring width (B) of 336.55 mm. This configuration yields an effective cross-sectional wall thickness of 69.8 mm and an envelope ratio (D/d) of 1.32, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 777/431XTM 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.
