Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 71907 CEGA/HCP4A 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 71907 CEGA/HCP4A with a precision bore diameter (d) of 35 mm, an outside diameter (D) of 55 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 71907 CEGA/HCP4A 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 35 mm bore. For the 55 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Every production batch of CHG Bearing 71907 CEGA/HCP4A Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
