EE755281D/755360 914.4 mm 711.2 mm Frequently Asked Questions about EE755281D/755360 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the EE755281D/755360 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE755281D/755360 with a precision bore diameter (d) of 711.2 mm, an outside diameter (D) of 914.4 mm, and a nominal ring width (B) of 149.225 mm. This configuration yields an effective cross-sectional wall thickness of 101.6 mm and an envelope ratio (D/d) of 1.29, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the EE755281D/755360 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.
For international ocean and air freight, CHG Bearing packs EE755281D/755360 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.
