7206 CD/P4A 62 mm 30 mm 16 mm Frequently Asked Questions about 7206 CD/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 7206 CD/P4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7206 CD/P4A with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 62 mm, and a nominal ring width (B) of 16 mm. This configuration yields an effective cross-sectional wall thickness of 16.0 mm and an envelope ratio (D/d) of 2.07, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7206 CD/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (30 mm x 62 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Each 7206 CD/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 (30 mm bore side) ensures perfect planar contact without edge binding.
