71915 CDGA/HCP4A 105 mm 75 mm 16 mm Frequently Asked Questions about 71915 CDGA/HCP4A Super-precision Angular Contact 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 71915 CDGA/HCP4A with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 105 mm, and a nominal ring width (B) of 16 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.4, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 71915 CDGA/HCP4A inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
To ensure optimum performance of CHG Bearing 71915 CDGA/HCP4A 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 75 mm bore. For the 105 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 71915 CDGA/HCP4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
