Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing HWAD426HP4 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To match diverse operational dynamics, CHG Bearing supplies HWAD426HP4 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAD426HP4 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAD426HP4 with a precision bore diameter (d) of 41.275 mm, an outside diameter (D) of 47.625 mm, and a nominal ring width (B) of 7.937 mm. This configuration yields an effective cross-sectional wall thickness of 3.2 mm and an envelope ratio (D/d) of 1.15, delivering compact rigidity for OEM machinery housings.
