Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 71806 CDGB/P4 Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71806 CDGB/P4 with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 7 mm. This configuration yields an effective cross-sectional wall thickness of 6.0 mm and an envelope ratio (D/d) of 1.4, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 71806 CDGB/P4 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.
As standard production, CHG Bearing subjects 71806 CDGB/P4 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.
