Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 792/1000G2K over a 1000 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Engineered according to international ISO boundary plans, CHG Bearing supplies 792/1000G2K with a precision bore diameter (d) of 1000 mm, an outside diameter (D) of 1270 mm, and a nominal ring width (B) of 100 mm. This configuration yields an effective cross-sectional wall thickness of 135.0 mm and an envelope ratio (D/d) of 1.27, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 792/1000G2K 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.
The CHG Bearing 792/1000G2K 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.
