7048 CD/P4ADGA 360 mm 240 mm 112 mm Frequently Asked Questions about 7048 CD/P4ADGA 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 7048 CD/P4ADGA with a precision bore diameter (d) of 240 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 112 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7048 CD/P4ADGA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (240 mm x 360 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
For international ocean and air freight, CHG Bearing packs 7048 CD/P4ADGA with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To ensure optimum performance of CHG Bearing 7048 CD/P4ADGA 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 240 mm bore. For the 360 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
