Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 4TR570CGWHCS80 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 4TR570CGWHCS80 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Beyond standard alloy steel, CHG Bearing can customize the 4TR570CGWHCS80 Four-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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 4TR570CGWHCS80 with a precision bore diameter (d) of 570 mm, an outside diameter (D) of 810 mm, and a nominal ring width (B) of 590 mm. This configuration yields an effective cross-sectional wall thickness of 120.0 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
