Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NNCF4856V. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies NNCF4856V with a precision bore diameter (d) of 280 mm, an outside diameter (D) of 350 mm, and a nominal ring width (B) of 69 mm. This configuration yields an effective cross-sectional wall thickness of 35.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
Model NNCF4856V 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 280 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing NNCF4856V Full Complement Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NNCF4856V, FAG NNCF4856V, NSK NNCF4856V. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
