The DAC43790041/38 is a heavy-duty, Generation 1 (Gen 1) auto wheel hub bearing featuring a unique stepped inner/outer width of 43 mm (ID) × 79 mm (OD) × 41/38 mm (Width). Engineered as a double-row angular contact ball bearing, it provides exceptional stability to handle simultaneous radial and axial (thrust) loads under extreme road stress. Fully sealed to block out dust and moisture, it is a direct OEM replacement for the front axles of popular passenger cars, including Ford, Mercury, and Honda models. We supply B2B auto parts distributors with high-quality aftermarket equivalents, robust packaging, and competitive bulk pricing.
The DAC43790041/38 Wheel Bearing (also cross-referenced as DAC4379W-1CS57 or 43BWD08) is specifically designed to keep vehicle steering alignments tight and wheels completely stable. The double-row angular contact geometry allows the bearing to manage heavy radial forces (the resting weight of the car) and intense axial thrust loads (the side-to-side forces generated during cornering) within a single compact unit. By integrating two rows of balls into one assembly, the internal clearance is precisely set at the factory, eliminating the need for manual adjustments by the installing mechanic.
This specific DAC bearing features an asymmetrical width (the inner ring is wider than the outer ring), which is critical for proper installation on the axle spindle.

Sourcing high-quality Gen 1 hub bearings is essential for Independent Aftermarket (IAM) distributors to prevent costly warranty returns:
Asymmetrical Width Design: The 41mm inner ring paired with the 38mm outer ring ensures a perfect, secure fitment onto specific front axle steering knuckles and hubs.
Harsh Environment Protection: The double closures (metal shields or rubber seals) lock in the factory-applied, high-temperature grease while creating an impenetrable barrier against road debris, water, and brake dust.
Smooth & Quiet Operation: Premium GCr15 bearing steel and micro-polished raceways guarantee low friction, extending the bearing's life and ensuring a quiet ride for the end-user.
This bearing is a high-volume replacement part widely utilized in passenger car front-wheel drivetrains:
Ford Escort (1991–2003)
Mercury Tracer (1991–1999)
Honda Civic / City / Integra (various 1990s–2000s models)
We support global auto parts wholesalers, repair chains, and brand owners with flexible, high-capacity manufacturing.
Customization: We offer neutral industrial packaging or fully customized OEM retail boxes tailored to your brand.
Seal Options: Available with standard metal shields (ZZ) for low friction, or heavy-duty rubber seals (2RS/2RZ) for maximum water resistance depending on your regional market requirements.
Delivery & Supply: Fast turnaround times with flexible shipping options (Air/Sea) and standard T/T or L/C payment terms.
