HWA9112HP4 192.0875 mm 177.8 mm 6.35 mm Frequently Asked Questions about HWA9112HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HWA9112HP4 over a 177.8 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Beyond standard alloy steel, CHG Bearing can customize the HWA9112HP4 Thin Section Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWA9112HP4 with a precision bore diameter (d) of 177.8 mm, an outside diameter (D) of 192.0875 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 1.08, delivering compact rigidity for OEM machinery housings.
