Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 5397/2000 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 2000 mm) and steep thermal gradients between inner and outer rings.
The CHG Bearing 5397/2000 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 5397/2000 with a precision bore diameter (d) of 2000 mm, an outside diameter (D) of 2500 mm, and a nominal ring width (B) of 190 mm. This configuration yields an effective cross-sectional wall thickness of 250.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 5397/2000 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.
