Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 10938300 Four-Point Contact Ball 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.
Absolutely. The CHG Bearing 10938300 Four-Point Contact Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 10938300, FAG 10938300, NSK 10938300. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Engineered according to international ISO boundary plans, CHG Bearing supplies 10938300 with a precision bore diameter (d) of 572 mm, an outside diameter (D) of 716 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 72.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 10938300 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.
