Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 46T30324JR/145 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.
Sourcing 46T30324JR/145 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Double Row Tapered Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T30324JR/145 with a precision bore diameter (d) of 120 mm, an outside diameter (D) of 260 mm, and a nominal ring width (B) of 188 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 2.17, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for 46T30324JR/145 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.
