Frequently Asked Questions about 7214 ACD/HCP4ADGA Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

Each 7214 ACD/HCP4ADGA 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.
Model 7214 ACD/HCP4ADGA 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.
To match diverse operational dynamics, CHG Bearing supplies 7214 ACD/HCP4ADGA with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
The Open Type engineered for 7214 ACD/HCP4ADGA by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
