46T403215 320 mm 200 mm Frequently Asked Questions about 46T403215 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 46T403215 Double Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T403215 with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 320 mm, and a nominal ring width (B) of 146 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 1.6, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 46T403215 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.
Quality starts with raw material selection: CHG Bearing crafts 46T403215 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.
