Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing HWA972HP4 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Thin Section Angular Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWA972HP4 with a precision bore diameter (d) of 114.3 mm, an outside diameter (D) of 128.5875 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 7.1 mm and an envelope ratio (D/d) of 1.12, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing HWA972HP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (114.3 mm x 128.5875 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model HWA972HP4 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 114.3 mm) and steep thermal gradients between inner and outer rings.
