EE275108/275156D 393.7 mm 273.05 mm Frequently Asked Questions about EE275108/275156D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each EE275108/275156D produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (273.05 mm bore side) ensures perfect planar contact without edge binding.
In its sealed configuration (Open Type), CHG Bearing pre-charges EE275108/275156D with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE275108/275156D with a precision bore diameter (d) of 273.05 mm, an outside diameter (D) of 393.7 mm, and a nominal ring width (B) of 157.163 mm. This configuration yields an effective cross-sectional wall thickness of 60.3 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
