Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts HRE30025 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies HRE30025 with a precision bore diameter (d) of 300 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 25 mm. This configuration yields an effective cross-sectional wall thickness of 30.0 mm and an envelope ratio (D/d) of 1.2, delivering compact rigidity for OEM machinery housings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for HRE30025. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
As standard production, CHG Bearing subjects HRE30025 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.
