7022 CDGB/P4A 170 mm 110 mm 28 mm Frequently Asked Questions about 7022 CDGB/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 7022 CDGB/P4A over a 110 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 safeguard CHG Bearing 7022 CDGB/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (110 mm x 170 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Each 7022 CDGB/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 (110 mm bore side) ensures perfect planar contact without edge binding.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7022 CDGB/P4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
