Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 797/1320G2K3 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.
The CHG Bearing 797/1320G2K3 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 797/1320G2K3 with a precision bore diameter (d) of 1320 mm, an outside diameter (D) of 1720 mm, and a nominal ring width (B) of 134 mm. This configuration yields an effective cross-sectional wall thickness of 200.0 mm and an envelope ratio (D/d) of 1.3, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 797/1320G2K3 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
