71813 ACD/HCP4 85 mm 65 mm 10 mm Frequently Asked Questions about 71813 ACD/HCP4 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 71813 ACD/HCP4 Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 65 mm bore. For the 85 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Sourcing 71813 ACD/HCP4 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
As standard production, CHG Bearing subjects 71813 ACD/HCP4 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 71813 ACD/HCP4 with a precision bore diameter (d) of 65 mm, an outside diameter (D) of 85 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 1.31, delivering compact rigidity for OEM machinery housings.
