Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 7020 ACB/HCP4AQBCA with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7020 ACB/HCP4AQBCA with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 96 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 7020 ACB/HCP4AQBCA 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.
To ensure optimum performance of CHG Bearing 7020 ACB/HCP4AQBCA 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 100 mm bore. For the 150 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
