Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 462/630A with a precision bore diameter (d) of 630 mm, an outside diameter (D) of 920 mm, and a nominal ring width (B) of 265 mm. This configuration yields an effective cross-sectional wall thickness of 145.0 mm and an envelope ratio (D/d) of 1.46, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 462/630A 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.
Quality starts with raw material selection: CHG Bearing crafts 462/630A 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.
Model 462/630A is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 630 mm) and steep thermal gradients between inner and outer rings.
