Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 1797/1915G2 Crossed Roller Slewing Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 1797/1915G2 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Quality starts with raw material selection: CHG Bearing crafts 1797/1915G2 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 1797/1915G2 with a precision bore diameter (d) of 1915 mm, an outside diameter (D) of 2420 mm, and a nominal ring width (B) of 140 mm. This configuration yields an effective cross-sectional wall thickness of 252.5 mm and an envelope ratio (D/d) of 1.26, delivering compact rigidity for OEM machinery housings.
