7020 ACEGB/P4A 150 mm 100 mm 24 mm Frequently Asked Questions about 7020 ACEGB/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7020 ACEGB/P4A 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 (100 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7020 ACEGB/P4A with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
Yes, 100% of 7020 ACEGB/P4A Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Quality starts with raw material selection: CHG Bearing crafts 7020 ACEGB/P4A 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.
