Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for EE722112D/722185. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Sourcing EE722112D/722185 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.
The CHG Bearing EE722112D/722185 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 EE722112D/722185 with a precision bore diameter (d) of 279.4 mm, an outside diameter (D) of 469.9 mm, and a nominal ring width (B) of 169.863 mm. This configuration yields an effective cross-sectional wall thickness of 95.2 mm and an envelope ratio (D/d) of 1.68, delivering compact rigidity for OEM machinery housings.
