Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 7022 ACDGA/HCP4A directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7022 ACDGA/HCP4A with a precision bore diameter (d) of 110 mm, an outside diameter (D) of 170 mm, and a nominal ring width (B) of 28 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 ensure optimum performance of CHG Bearing 7022 ACDGA/HCP4A Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 110 mm bore. For the 170 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 7022 ACDGA/HCP4A 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.
