HKAA010XP4 34.925 mm 25.4 mm 4.7625 mm Frequently Asked Questions about HKAA010XP4 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HKAA010XP4 Thin Section Four-Point Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 25.4 mm bore. For the 34.925 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 HKAA010XP4 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKAA010XP4 with a precision bore diameter (d) of 25.4 mm, an outside diameter (D) of 34.925 mm, and a nominal ring width (B) of 4.7625 mm. This configuration yields an effective cross-sectional wall thickness of 4.8 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing HKAA010XP4 Thin Section Four-Point Contact Ball 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.
