7208 CD/P4ADGA 80 mm 40 mm 36 mm Frequently Asked Questions about 7208 CD/P4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7208 CD/P4ADGA with a precision bore diameter (d) of 40 mm, an outside diameter (D) of 80 mm, and a nominal ring width (B) of 36 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 2.0, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 7208 CD/P4ADGA 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.
Beyond standard alloy steel, CHG Bearing can customize the 7208 CD/P4ADGA 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.
To extend the trouble-free lifespan of CHG Bearing 7208 CD/P4ADGA, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
