Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing EE231401D/232025 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.
As standard production, CHG Bearing subjects EE231401D/232025 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for EE231401D/232025. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE231401D/232025 with a precision bore diameter (d) of 355.6 mm, an outside diameter (D) of 514.35 mm, and a nominal ring width (B) of 127 mm. This configuration yields an effective cross-sectional wall thickness of 79.4 mm and an envelope ratio (D/d) of 1.45, delivering compact rigidity for OEM machinery housings.
