7214 ACDGB/HCP4A 125 mm 70 mm 24 mm Frequently Asked Questions about 7214 ACDGB/HCP4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 7214 ACDGB/HCP4A is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 70 mm) and steep thermal gradients between inner and outer rings.
Each 7214 ACDGB/HCP4A 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 (70 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7214 ACDGB/HCP4A with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 125 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 27.5 mm and an envelope ratio (D/d) of 1.79, delivering compact rigidity for OEM machinery housings.
Sourcing 7214 ACDGB/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.
