Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NF18/750 Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NF18/750, FAG NF18/750, NSK NF18/750. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model NF18/750 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 750 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies NF18/750 with a precision bore diameter (d) of 750 mm, an outside diameter (D) of 920 mm, and a nominal ring width (B) of 78 mm. This configuration yields an effective cross-sectional wall thickness of 85.0 mm and an envelope ratio (D/d) of 1.23, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing NF18/750 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.
