618/950P4 1150 mm 950 mm 90 mm Frequently Asked Questions about 618/950P4 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
For international ocean and air freight, CHG Bearing packs 618/950P4 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 618/950P4 with a precision bore diameter (d) of 950 mm, an outside diameter (D) of 1150 mm, and a nominal ring width (B) of 90 mm. This configuration yields an effective cross-sectional wall thickness of 100.0 mm and an envelope ratio (D/d) of 1.21, delivering compact rigidity for OEM machinery housings.
Model 618/950P4 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 950 mm) and steep thermal gradients between inner and outer rings.
Beyond standard alloy steel, CHG Bearing can customize the 618/950P4 Deep Groove Ball Bearings（618 / 619 SERIES） 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.
