Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 802245 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.
To ensure optimum performance of CHG Bearing 802245 Four-Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 300 mm bore. For the 460 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 802245 with a precision bore diameter (d) of 300 mm, an outside diameter (D) of 460 mm, and a nominal ring width (B) of 390 mm. This configuration yields an effective cross-sectional wall thickness of 80.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
Yes, 100% of 802245 Four-Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
