Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the S7001 ACEGC/P4A Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
In its sealed configuration (Non-contact Seal), CHG Bearing pre-charges S7001 ACEGC/P4A 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 S7001 ACEGC/P4A 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 S7001 ACEGC/P4A with a precision bore diameter (d) of 12 mm, an outside diameter (D) of 28 mm, and a nominal ring width (B) of 8 mm. This configuration yields an effective cross-sectional wall thickness of 8.0 mm and an envelope ratio (D/d) of 2.33, delivering compact rigidity for OEM machinery housings.
