EE128102/128160D 406.4 mm 260.35 mm 149.225 mm Frequently Asked Questions about EE128102/128160D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing EE128102/128160D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260.35 mm x 406.4 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 EE128102/128160D with a precision bore diameter (d) of 260.35 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 73.0 mm and an envelope ratio (D/d) of 1.56, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs EE128102/128160D 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.
As standard production, CHG Bearing subjects EE128102/128160D to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
