Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 7014 CD/HCP4AQBCA Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 70 mm bore. For the 110 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
When fitting 7014 CD/HCP4AQBCA 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 7014 CD/HCP4AQBCA 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.
To match diverse operational dynamics, CHG Bearing supplies 7014 CD/HCP4AQBCA 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.
