EE231400/231976D 501.65 mm 355.6 mm Frequently Asked Questions about EE231400/231976D 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 EE231400/231976D 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.
The Open Type engineered for EE231400/231976D 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE231400/231976D with a precision bore diameter (d) of 355.6 mm, an outside diameter (D) of 501.65 mm, and a nominal ring width (B) of 155.575 mm. This configuration yields an effective cross-sectional wall thickness of 73.0 mm and an envelope ratio (D/d) of 1.41, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for EE231400/231976D, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
