EE671801/672875D 730.148 mm 457.2 mm Frequently Asked Questions about EE671801/672875D 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 EE671801/672875D with a precision bore diameter (d) of 457.2 mm, an outside diameter (D) of 730.148 mm, and a nominal ring width (B) of 254 mm. This configuration yields an effective cross-sectional wall thickness of 136.5 mm and an envelope ratio (D/d) of 1.6, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing EE671801/672875D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 457.2 mm bore. For the 730.148 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The CHG Bearing EE671801/672875D is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Absolutely. The CHG Bearing EE671801/672875D Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF EE671801/672875D, FAG EE671801/672875D, NSK EE671801/672875D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
