45396 790 mm 480 mm Frequently Asked Questions about 45396 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 45396 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.
For international ocean and air freight, CHG Bearing packs 45396 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Built for demanding industrial environments, the 45396 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 45396 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.
