Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 440TD0720-2 Double 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.
Built for demanding industrial environments, the 440TD0720-2 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.
To safeguard CHG Bearing 440TD0720-2 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (440 mm x 720 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Engineered according to international ISO boundary plans, CHG Bearing supplies 440TD0720-2 with a precision bore diameter (d) of 440 mm, an outside diameter (D) of 720 mm, and a nominal ring width (B) of 283 mm. This configuration yields an effective cross-sectional wall thickness of 140.0 mm and an envelope ratio (D/d) of 1.64, delivering compact rigidity for OEM machinery housings.
