Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies M268749DW/710/710DP5 with a precision bore diameter (d) of 415.925 mm, an outside diameter (D) of 590.55 mm, and a nominal ring width (B) of 434.975 mm. This configuration yields an effective cross-sectional wall thickness of 87.3 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the M268749DW/710/710DP5 Four-Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
In its sealed configuration (Open Type), CHG Bearing pre-charges M268749DW/710/710DP5 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.
Standard batches of CHG Bearing M268749DW/710/710DP5 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
