7397/2700G2K 3150 mm 2700 mm 4085 mm 3740 mm 255 mm Frequently Asked Questions about 7397/2700G2K Three-row Cylindrical Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7397/2700G2K produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (2700 mm bore side) ensures perfect planar contact without edge binding.
To extend the trouble-free lifespan of CHG Bearing 7397/2700G2K, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
As standard production, CHG Bearing subjects 7397/2700G2K 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7397/2700G2K with a precision bore diameter (d) of 2700 mm, an outside diameter (D) of 3150 mm, and a nominal ring width (B) of 255 mm. This configuration yields an effective cross-sectional wall thickness of 225.0 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
