EE736173D/238/239D 609.524 mm 432.003 mm 317.5 mm Frequently Asked Questions about EE736173D/238/239D Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each EE736173D/238/239D 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 (432.003 mm bore side) ensures perfect planar contact without edge binding.
The Open Type engineered for EE736173D/238/239D 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.
Sourcing EE736173D/238/239D 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 Four-Row Tapered Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies EE736173D/238/239D with a precision bore diameter (d) of 432.003 mm, an outside diameter (D) of 609.524 mm, and a nominal ring width (B) of 317.5 mm. This configuration yields an effective cross-sectional wall thickness of 88.8 mm and an envelope ratio (D/d) of 1.41, delivering compact rigidity for OEM machinery housings.
