M249748DW/710/710DP5 358.775 mm 254 mm 269.875 mm Frequently Asked Questions about M249748DW/710/710DP5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects M249748DW/710/710DP5 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Engineered according to international ISO boundary plans, CHG Bearing supplies M249748DW/710/710DP5 with a precision bore diameter (d) of 254 mm, an outside diameter (D) of 358.775 mm, and a nominal ring width (B) of 269.875 mm. This configuration yields an effective cross-sectional wall thickness of 52.4 mm and an envelope ratio (D/d) of 1.41, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing M249748DW/710/710DP5 Four-Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
When fitting M249748DW/710/710DP5 over a 254 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
