Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each S71918 ACE/P4ADBA produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (90 mm bore side) ensures perfect planar contact without edge binding.
Every production batch of CHG Bearing S71918 ACE/P4ADBA 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies S71918 ACE/P4ADBA with a precision bore diameter (d) of 90 mm, an outside diameter (D) of 125 mm, and a nominal ring width (B) of 36 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.39, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs S71918 ACE/P4ADBA 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.
