Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 011.20.944.03 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 011.20.944.03 with a precision bore diameter (d) of 834.136 mm, an outside diameter (D) of 1046.48 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 106.2 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for 011.20.944.03 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.
Every production batch of CHG Bearing 011.20.944.03 Four-Point Contact Ball Slewing Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
