Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 3806/530 Four-Row Tapered Roller 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.
Quality starts with raw material selection: CHG Bearing crafts 3806/530 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.
To match diverse operational dynamics, CHG Bearing supplies 3806/530 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Absolutely. The CHG Bearing 3806/530 Four-Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 3806/530, FAG 3806/530, NSK 3806/530. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
