HWAA12160HP4 273.05 mm 254 mm 19.05 mm 266.49 mm 260.56082 mm Frequently Asked Questions about HWAA12160HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects HWAA12160HP4 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.
Yes, 100% of HWAA12160HP4 Super Duplex Angular Contact Ball 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.
To ensure optimum performance of CHG Bearing HWAA12160HP4 Super Duplex Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 254 mm bore. For the 273.05 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 HWAA12160HP4 with a precision bore diameter (d) of 254 mm, an outside diameter (D) of 273.05 mm, and a nominal ring width (B) of 19.05 mm. This configuration yields an effective cross-sectional wall thickness of 9.5 mm and an envelope ratio (D/d) of 1.07, delivering compact rigidity for OEM machinery housings.
