HKC047XP0 139.7 mm 120.65 mm 9.525 mm Frequently Asked Questions about HKC047XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the HKC047XP0 Thin Section Four-Point Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Model HKC047XP0 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 120.65 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKC047XP0 with a precision bore diameter (d) of 120.65 mm, an outside diameter (D) of 139.7 mm, and a nominal ring width (B) of 9.525 mm. This configuration yields an effective cross-sectional wall thickness of 9.5 mm and an envelope ratio (D/d) of 1.16, delivering compact rigidity for OEM machinery housings.
The CHG Bearing HKC047XP0 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
