Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7397/2700GK1 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.
To match diverse operational dynamics, CHG Bearing supplies 7397/2700GK1 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.
Absolutely. The CHG Bearing 7397/2700GK1 Three-row Cylindrical Roller Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7397/2700GK1, FAG 7397/2700GK1, NSK 7397/2700GK1. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The Open Type engineered for 7397/2700GK1 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
