Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 7012 ACE/HCP4AH1DT 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7012 ACE/HCP4AH1DT with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
The CHG Bearing 7012 ACE/HCP4AH1DT is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7012 ACE/HCP4AH1DT with a precision bore diameter (d) of 60 mm, an outside diameter (D) of 95 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 1.58, delivering compact rigidity for OEM machinery housings.
