EE790119D/790221 558.8 mm 304.8 mm Frequently Asked Questions about EE790119D/790221 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model EE790119D/790221 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 304.8 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE790119D/790221 with a precision bore diameter (d) of 304.8 mm, an outside diameter (D) of 558.8 mm, and a nominal ring width (B) of 285.75 mm. This configuration yields an effective cross-sectional wall thickness of 127.0 mm and an envelope ratio (D/d) of 1.83, delivering compact rigidity for OEM machinery housings.
Each EE790119D/790221 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (304.8 mm bore side) ensures perfect planar contact without edge binding.
Sourcing EE790119D/790221 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 Double Row Tapered Roller Bearings.
