HWA1372HP4 134.9375 mm 114.3 mm 7.937 mm Frequently Asked Questions about HWA1372HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing HWA1372HP4 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWA1372HP4 with a precision bore diameter (d) of 114.3 mm, an outside diameter (D) of 134.9375 mm, and a nominal ring width (B) of 7.937 mm. This configuration yields an effective cross-sectional wall thickness of 10.3 mm and an envelope ratio (D/d) of 1.18, delivering compact rigidity for OEM machinery housings.
Model HWA1372HP4 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.
To ensure optimum performance of CHG Bearing HWA1372HP4 Thin Section Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 114.3 mm bore. For the 134.9375 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
