FC3246168 230 mm 160 mm 180 mm 168 mm Frequently Asked Questions about FC3246168 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model FC3246168 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 160 mm) and steep thermal gradients between inner and outer rings.
In its sealed configuration (Open Type), CHG Bearing pre-charges FC3246168 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Engineered according to international ISO boundary plans, CHG Bearing supplies FC3246168 with a precision bore diameter (d) of 160 mm, an outside diameter (D) of 230 mm, and a nominal ring width (B) of 168 mm. This configuration yields an effective cross-sectional wall thickness of 35.0 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing FC3246168 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
