S7018 ACD/P4ADBB 140 mm 90 mm 48 mm Frequently Asked Questions about S7018 ACD/P4ADBB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7018 ACD/P4ADBB with a precision bore diameter (d) of 90 mm, an outside diameter (D) of 140 mm, and a nominal ring width (B) of 48 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.56, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing S7018 ACD/P4ADBB Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF S7018 ACD/P4ADBB, FAG S7018 ACD/P4ADBB, NSK S7018 ACD/P4ADBB. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To ensure optimum performance of CHG Bearing S7018 ACD/P4ADBB 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 90 mm bore. For the 140 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The Non-contact Seal engineered for S7018 ACD/P4ADBB 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.
