Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing D797/1320G2K2 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Engineered according to international ISO boundary plans, CHG Bearing supplies D797/1320G2K2 with a precision bore diameter (d) of 1320 mm, an outside diameter (D) of 1719 mm, and a nominal ring width (B) of 134 mm. This configuration yields an effective cross-sectional wall thickness of 199.5 mm and an envelope ratio (D/d) of 1.3, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects D797/1320G2K2 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.
Model D797/1320G2K2 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 1320 mm) and steep thermal gradients between inner and outer rings.
