S71926 ACD/P4A 180 mm 130 mm 24 mm Frequently Asked Questions about S71926 ACD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To extend the trouble-free lifespan of CHG Bearing S71926 ACD/P4A, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Engineered according to international ISO boundary plans, CHG Bearing supplies S71926 ACD/P4A with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 180 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing S71926 ACD/P4A 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 130 mm bore. For the 180 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Absolutely. The CHG Bearing S71926 ACD/P4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF S71926 ACD/P4A, FAG S71926 ACD/P4A, NSK S71926 ACD/P4A.
