7020 ACD/P4ATGA 150 mm 100 mm 72 mm Frequently Asked Questions about 7020 ACD/P4ATGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 7020 ACD/P4ATGA Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Model 7020 ACD/P4ATGA 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7020 ACD/P4ATGA. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
To match diverse operational dynamics, CHG Bearing supplies 7020 ACD/P4ATGA with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
