EE128114/128160D 406.4 mm 280 mm Frequently Asked Questions about EE128114/128160D 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 EE128114/128160D with a precision bore diameter (d) of 280 mm, an outside diameter (D) of 406.4 mm, and a nominal ring width (B) of 149.225 mm. This configuration yields an effective cross-sectional wall thickness of 63.2 mm and an envelope ratio (D/d) of 1.45, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the EE128114/128160D 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.
To match diverse operational dynamics, CHG Bearing supplies EE128114/128160D with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
For international ocean and air freight, CHG Bearing packs EE128114/128160D 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.
