Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the HWAD988HP4 Super Duplex Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To safeguard CHG Bearing HWAD988HP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (139.7 mm x 153.9875 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for HWAD988HP4, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
To match diverse operational dynamics, CHG Bearing supplies HWAD988HP4 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.
