Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71806 CD/P4DGA with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 6.0 mm and an envelope ratio (D/d) of 1.4, delivering compact rigidity for OEM machinery housings.
Sourcing 71806 CD/P4DGA 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.
To ensure optimum performance of CHG Bearing 71806 CD/P4DGA 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 42 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 71806 CD/P4DGA 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.
