EE291175/291751D 444.5 mm 298.45 mm Frequently Asked Questions about EE291175/291751D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges EE291175/291751D 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 EE291175/291751D with a precision bore diameter (d) of 298.45 mm, an outside diameter (D) of 444.5 mm, and a nominal ring width (B) of 146.05 mm. This configuration yields an effective cross-sectional wall thickness of 73.0 mm and an envelope ratio (D/d) of 1.49, delivering compact rigidity for OEM machinery housings.
Yes, 100% of EE291175/291751D Double Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
The Open Type engineered for EE291175/291751D 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.
