Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 46T806021 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T806021 with a precision bore diameter (d) of 400 mm, an outside diameter (D) of 600 mm, and a nominal ring width (B) of 205 mm. This configuration yields an effective cross-sectional wall thickness of 100.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 46T806021 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 46T806021 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.
