Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 7204 CDGA/P4A 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 a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7204 CDGA/P4A. 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 7204 CDGA/P4A with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 47 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 13.5 mm and an envelope ratio (D/d) of 2.35, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 7204 CDGA/P4A 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.
