Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 7014 ACE/HCP4AH1DBA 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.
Standard batches of CHG Bearing 7014 ACE/HCP4AH1DBA conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
The Open Type engineered for 7014 ACE/HCP4AH1DBA 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7014 ACE/HCP4AH1DBA with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 110 mm, and a nominal ring width (B) of 40 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
