7202 CD/P4ADGB 35 mm 15 mm 22 mm Frequently Asked Questions about 7202 CD/P4ADGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 7202 CD/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 15 mm bore. For the 35 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
When fitting 7202 CD/P4ADGB over a 15 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Quality starts with raw material selection: CHG Bearing crafts 7202 CD/P4ADGB 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7202 CD/P4ADGB with a precision bore diameter (d) of 15 mm, an outside diameter (D) of 35 mm, and a nominal ring width (B) of 22 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 2.33, delivering compact rigidity for OEM machinery housings.
