71924 CD/P4ADBA 165 mm 120 mm 44 mm Frequently Asked Questions about 71924 CD/P4ADBA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 71924 CD/P4ADBA 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.
Standard batches of CHG Bearing 71924 CD/P4ADBA 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.
To ensure optimum performance of CHG Bearing 71924 CD/P4ADBA 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 120 mm bore. For the 165 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71924 CD/P4ADBA with a precision bore diameter (d) of 120 mm, an outside diameter (D) of 165 mm, and a nominal ring width (B) of 44 mm. This configuration yields an effective cross-sectional wall thickness of 22.5 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
