Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 7217 CD/P4ADGA 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.
Each 7217 CD/P4ADGA 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 (85 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7217 CD/P4ADGA with a precision bore diameter (d) of 85 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 32.5 mm and an envelope ratio (D/d) of 1.76, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 7217 CD/P4ADGA, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
