HWAD888HP4 152.4 mm 139.7 mm 9.525 mm 147.53082 mm 144.55902 mm Frequently Asked Questions about HWAD888HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the HWAD888HP4 Super Duplex 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 HWAD888HP4 with a precision bore diameter (d) of 139.7 mm, an outside diameter (D) of 152.4 mm, and a nominal ring width (B) of 9.525 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.09, delivering compact rigidity for OEM machinery housings.
Model HWAD888HP4 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 139.7 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs HWAD888HP4 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
