Frequently Asked Questions about 7008 CE/HCP4AH1DGA Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7008 CE/HCP4AH1DGA. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7008 CE/HCP4AH1DGA with a precision bore diameter (d) of 40 mm, an outside diameter (D) of 68 mm, and a nominal ring width (B) of 30 mm. This configuration yields an effective cross-sectional wall thickness of 14.0 mm and an envelope ratio (D/d) of 1.7, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 7008 CE/HCP4AH1DGA 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 40 mm bore. For the 68 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
For international ocean and air freight, CHG Bearing packs 7008 CE/HCP4AH1DGA 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.
