71822 CDGB/P4 140 mm 110 mm 16 mm Frequently Asked Questions about 71822 CDGB/P4 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 71822 CDGB/P4 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.
Beyond standard alloy steel, CHG Bearing can customize the 71822 CDGB/P4 Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71822 CDGB/P4 with a precision bore diameter (d) of 110 mm, an outside diameter (D) of 140 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 1.27, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 71822 CDGB/P4 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 110 mm bore. For the 140 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
