HWA733HP4 63.5 mm 52.3875 mm 6.35 mm Frequently Asked Questions about HWA733HP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWA733HP4 with a precision bore diameter (d) of 52.3875 mm, an outside diameter (D) of 63.5 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 5.6 mm and an envelope ratio (D/d) of 1.21, delivering compact rigidity for OEM machinery housings.
Model HWA733HP4 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 52.3875 mm) and steep thermal gradients between inner and outer rings.
Beyond standard alloy steel, CHG Bearing can customize the HWA733HP4 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.
Yes, 100% of HWA733HP4 Thin Section Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
