EE128111/160CD/X2S 406.4 mm 280.192 mm Frequently Asked Questions about EE128111/160CD/X2S Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing EE128111/160CD/X2S is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE128111/160CD/X2S with a precision bore diameter (d) of 280.192 mm, an outside diameter (D) of 406.4 mm, and a nominal ring width (B) of 149.225 mm. This configuration yields an effective cross-sectional wall thickness of 63.1 mm and an envelope ratio (D/d) of 1.45, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing EE128111/160CD/X2S Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF EE128111/160CD/X2S, FAG EE128111/160CD/X2S, NSK EE128111/160CD/X2S. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As standard production, CHG Bearing subjects EE128111/160CD/X2S 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.
