EE542215/542291D 736.6 mm 546.1 mm Frequently Asked Questions about EE542215/542291D 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 EE542215/542291D with a precision bore diameter (d) of 546.1 mm, an outside diameter (D) of 736.6 mm, and a nominal ring width (B) of 165.1 mm. This configuration yields an effective cross-sectional wall thickness of 95.2 mm and an envelope ratio (D/d) of 1.35, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open Type), CHG Bearing pre-charges EE542215/542291D 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.
To safeguard CHG Bearing EE542215/542291D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (546.1 mm x 736.6 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Open Type engineered for EE542215/542291D by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
