S71906 CD/P4A 47 mm 30 mm 9 mm Frequently Asked Questions about S71906 CD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing S71906 CD/P4A correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Engineered according to international ISO boundary plans, CHG Bearing supplies S71906 CD/P4A with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 47 mm, and a nominal ring width (B) of 9 mm. This configuration yields an effective cross-sectional wall thickness of 8.5 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing S71906 CD/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 30 mm bore. For the 47 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for S71906 CD/P4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
