7220 ACD/P4ATBTB 180 mm 100 mm 102 mm Frequently Asked Questions about 7220 ACD/P4ATBTB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 7220 ACD/P4ATBTB over a 100 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To match diverse operational dynamics, CHG Bearing supplies 7220 ACD/P4ATBTB 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.
To safeguard CHG Bearing 7220 ACD/P4ATBTB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (100 mm x 180 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 7220 ACD/P4ATBTB 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.
