Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 7005 FEGA/HCP4A 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 25 mm) and steep thermal gradients between inner and outer rings.
The CHG Bearing 7005 FEGA/HCP4A 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7005 FEGA/HCP4A 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 7005 FEGA/HCP4A with a precision bore diameter (d) of 25 mm, an outside diameter (D) of 47 mm, and a nominal ring width (B) of 12 mm. This configuration yields an effective cross-sectional wall thickness of 11.0 mm and an envelope ratio (D/d) of 1.88, delivering compact rigidity for OEM machinery housings.
