Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 7018 CD/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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7018 CD/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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 7018 CD/P4ADBB, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
