Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 62FC44240 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Engineered according to international ISO boundary plans, CHG Bearing supplies 62FC44240 with a precision bore diameter (d) of 310 mm, an outside diameter (D) of 440 mm, and a nominal ring width (B) of 240 mm. This configuration yields an effective cross-sectional wall thickness of 65.0 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
Model 62FC44240 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 310 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing 62FC44240 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.
