804180 635 mm 539.75 mm Frequently Asked Questions about 804180 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 804180 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.
For international ocean and air freight, CHG Bearing packs 804180 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Quality starts with raw material selection: CHG Bearing crafts 804180 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 804180 with a precision bore diameter (d) of 539.75 mm, an outside diameter (D) of 635 mm, and a nominal ring width (B) of 120.65 mm. This configuration yields an effective cross-sectional wall thickness of 47.6 mm and an envelope ratio (D/d) of 1.18, delivering compact rigidity for OEM machinery housings.
