HWA1177HP4 139.7 mm 122.2375 mm 7.937 mm Frequently Asked Questions about HWA1177HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWA1177HP4 with a precision bore diameter (d) of 122.2375 mm, an outside diameter (D) of 139.7 mm, and a nominal ring width (B) of 7.937 mm. This configuration yields an effective cross-sectional wall thickness of 8.7 mm and an envelope ratio (D/d) of 1.14, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing HWA1177HP4 Thin Section Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWA1177HP4, FAG HWA1177HP4, NSK HWA1177HP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing HWA1177HP4 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Model HWA1177HP4 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 122.2375 mm) and steep thermal gradients between inner and outer rings.
