BT4B332773 595 mm 450 mm 368 mm Frequently Asked Questions about BT4B332773 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 BT4B332773 with a precision bore diameter (d) of 450 mm, an outside diameter (D) of 595 mm, and a nominal ring width (B) of 368 mm. This configuration yields an effective cross-sectional wall thickness of 72.5 mm and an envelope ratio (D/d) of 1.32, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing BT4B332773 Four-Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 450 mm bore. For the 595 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 BT4B332773 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.
Every production batch of CHG Bearing BT4B332773 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.
