7214 CD/HCP4A 125 mm 70 mm 24 mm Frequently Asked Questions about 7214 CD/HCP4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 7214 CD/HCP4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7214 CD/HCP4A, FAG 7214 CD/HCP4A, NSK 7214 CD/HCP4A. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model 7214 CD/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.
When fitting 7214 CD/HCP4A over a 70 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Quality starts with raw material selection: CHG Bearing crafts 7214 CD/HCP4A 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.
