EE790114/790223D 558.8 mm 292.1 mm Frequently Asked Questions about EE790114/790223D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing EE790114/790223D Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To match diverse operational dynamics, CHG Bearing supplies EE790114/790223D 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.
The CHG Bearing EE790114/790223D 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 EE790114/790223D with a precision bore diameter (d) of 292.1 mm, an outside diameter (D) of 558.8 mm, and a nominal ring width (B) of 298.45 mm. This configuration yields an effective cross-sectional wall thickness of 133.3 mm and an envelope ratio (D/d) of 1.91, delivering compact rigidity for OEM machinery housings.
