7022 CD/P4ATGB 170 mm 110 mm 84 mm Frequently Asked Questions about 7022 CD/P4ATGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 7022 CD/P4ATGB Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7022 CD/P4ATGB with a precision bore diameter (d) of 110 mm, an outside diameter (D) of 170 mm, and a nominal ring width (B) of 84 mm. This configuration yields an effective cross-sectional wall thickness of 30.0 mm and an envelope ratio (D/d) of 1.55, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7022 CD/P4ATGB 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.
Quality starts with raw material selection: CHG Bearing crafts 7022 CD/P4ATGB inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
