Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing S71912 ACE/HCP4ADT directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies S71912 ACE/HCP4ADT with a precision bore diameter (d) of 60 mm, an outside diameter (D) of 85 mm, and a nominal ring width (B) of 26 mm. This configuration yields an effective cross-sectional wall thickness of 12.5 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
The Non-contact Seal engineered for S71912 ACE/HCP4ADT by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
For international ocean and air freight, CHG Bearing packs S71912 ACE/HCP4ADT 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.
