2TR400+DP 650 mm 400 mm Frequently Asked Questions about 2TR400+DP Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 2TR400+DP with a precision bore diameter (d) of 400 mm, an outside diameter (D) of 650 mm, and a nominal ring width (B) of 240 mm. This configuration yields an effective cross-sectional wall thickness of 125.0 mm and an envelope ratio (D/d) of 1.62, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 2TR400+DP 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 safeguard CHG Bearing 2TR400+DP against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (400 mm x 650 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Beyond standard alloy steel, CHG Bearing can customize the 2TR400+DP Double Row Tapered Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
