M383240D/210/210D 1016 mm 714.375 mm 704.85 mm Frequently Asked Questions about M383240D/210/210D Four-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 M383240D/210/210D with a precision bore diameter (d) of 714.375 mm, an outside diameter (D) of 1016 mm, and a nominal ring width (B) of 704.85 mm. This configuration yields an effective cross-sectional wall thickness of 150.8 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs M383240D/210/210D with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To ensure optimum performance of CHG Bearing M383240D/210/210D Four-Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 714.375 mm bore. For the 1016 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
As standard production, CHG Bearing subjects M383240D/210/210D 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.
