HWAA24112HP4 215.9 mm 177.8 mm 38.1 mm 207.77 mm 190.92926 mm Frequently Asked Questions about HWAA24112HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model HWAA24112HP4 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 177.8 mm) and steep thermal gradients between inner and outer rings.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAA24112HP4 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA24112HP4 with a precision bore diameter (d) of 177.8 mm, an outside diameter (D) of 215.9 mm, and a nominal ring width (B) of 38.1 mm. This configuration yields an effective cross-sectional wall thickness of 19.0 mm and an envelope ratio (D/d) of 1.21, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing HWAA24112HP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (177.8 mm x 215.9 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
