HWAA2468HP4 146.05 mm 107.95 mm 38.1 mm 132.92 mm 121.07926 mm Frequently Asked Questions about HWAA2468HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open / Single-Sided Sealed / Double-Sided Sealed), CHG Bearing pre-charges HWAA2468HP4 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.
Model HWAA2468HP4 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 107.95 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA2468HP4 with a precision bore diameter (d) of 107.95 mm, an outside diameter (D) of 146.05 mm, and a nominal ring width (B) of 38.1 mm. This configuration yields an effective cross-sectional wall thickness of 19.1 mm and an envelope ratio (D/d) of 1.35, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing HWAA2468HP4, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
