HWAA864HP4 114.3 mm 101.6 mm 12.7 mm 109.92 mm 105.9688 mm Frequently Asked Questions about HWAA864HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts HWAA864HP4 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
To ensure optimum performance of CHG Bearing HWAA864HP4 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 101.6 mm bore. For the 114.3 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA864HP4 with a precision bore diameter (d) of 101.6 mm, an outside diameter (D) of 114.3 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.12, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for HWAA864HP4, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
