7001 CE/HCP4ADBA 28 mm 12 mm 16 mm Frequently Asked Questions about 7001 CE/HCP4ADBA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7001 CE/HCP4ADBA 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 (12 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts 7001 CE/HCP4ADBA inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7001 CE/HCP4ADBA with a precision bore diameter (d) of 12 mm, an outside diameter (D) of 28 mm, and a nominal ring width (B) of 16 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.
The CHG Bearing 7001 CE/HCP4ADBA 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.
