46396 790 mm 480 mm Frequently Asked Questions about 46396 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 46396 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.
As standard production, CHG Bearing subjects 46396 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46396 with a precision bore diameter (d) of 480 mm, an outside diameter (D) of 790 mm, and a nominal ring width (B) of 248 mm. This configuration yields an effective cross-sectional wall thickness of 155.0 mm and an envelope ratio (D/d) of 1.65, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 46396 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (480 mm x 790 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
