Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 6397/2800GK2 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
As standard production, CHG Bearing subjects 6397/2800GK2 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 6397/2800GK2, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Sourcing 6397/2800GK2 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Three-row Cylindrical Roller Slewing Bearings.
