Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 45T908332A Double 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.
To ensure optimum performance of CHG Bearing 45T908332A Double 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 830 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 45T908332A with a precision bore diameter (d) of 450 mm, an outside diameter (D) of 830 mm, and a nominal ring width (B) of 288 mm. This configuration yields an effective cross-sectional wall thickness of 190.0 mm and an envelope ratio (D/d) of 1.84, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 45T908332A 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.
