HJA030CP4 88.9 mm 76.2 mm 6.35 mm Frequently Asked Questions about HJA030CP4 Thin Section Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HJA030CP4 with a precision bore diameter (d) of 76.2 mm, an outside diameter (D) of 88.9 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing HJA030CP4 Thin Section Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 76.2 mm bore. For the 88.9 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 HJA030CP4 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 HJA030CP4 Thin Section Deep Groove 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.
