71914 ACE/P4ADGB 100 mm 70 mm 32 mm Frequently Asked Questions about 71914 ACE/P4ADGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 71914 ACE/P4ADGB is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 70 mm) and steep thermal gradients between inner and outer rings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 71914 ACE/P4ADGB. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71914 ACE/P4ADGB with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 100 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.43, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 71914 ACE/P4ADGB 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 70 mm bore. For the 100 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
