7020 ACEGA/HCP4AL 150 mm 100 mm 24 mm Frequently Asked Questions about 7020 ACEGA/HCP4AL Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 7020 ACEGA/HCP4AL 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.
Model 7020 ACEGA/HCP4AL is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 100 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 7020 ACEGA/HCP4AL Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7020 ACEGA/HCP4AL, FAG 7020 ACEGA/HCP4AL, NSK 7020 ACEGA/HCP4AL. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 7020 ACEGA/HCP4AL 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.
