HWAA1169HP4 127 mm 109.5375 mm 15.875 mm 121.22912 mm 115.30584 mm Frequently Asked Questions about HWAA1169HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model HWAA1169HP4 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 109.5375 mm) and steep thermal gradients between inner and outer rings.
Sourcing HWAA1169HP4 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 Super Duplex Angular Contact Ball Bearings.
To safeguard CHG Bearing HWAA1169HP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (109.5375 mm x 127 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
To ensure optimum performance of CHG Bearing HWAA1169HP4 Super Duplex 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.
