HWA1169HP4 127 mm 109.5375 mm 7.937 mm Frequently Asked Questions about HWA1169HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing HWA1169HP4 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 HWA1169HP4 with a precision bore diameter (d) of 109.5375 mm, an outside diameter (D) of 127 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 1.16, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing HWA1169HP4 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 109.5375 mm bore. For the 127 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
In its sealed configuration (Open / Single-Sided Sealed / Double-Sided Sealed), CHG Bearing pre-charges HWA1169HP4 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.
