Frequently Asked Questions about S7014 CDGA/HCP4A Super-precision Angular Contact Ball Bearings

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

Standard batches of CHG Bearing S7014 CDGA/HCP4A 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.
Beyond standard alloy steel, CHG Bearing can customize the S7014 CDGA/HCP4A Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
When fitting S7014 CDGA/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.
To ensure optimum performance of CHG Bearing S7014 CDGA/HCP4A 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.
