Product Introduction

The DAC387437ABS is an advanced double-row wheel hub bearing integrating modern automotive braking technology. Sized at 38 x 74 x 37 mm, its defining feature is the built-in magnetic ABS (Anti-lock Braking System) encoder ring located on one side of the bearing seal. This integrated multi-pole magnetic ring communicates vital wheel speed data to the vehicle's ECU, ensuring safe and responsive braking. Manufactured with high-strength GCr15 steel, this bearing is an indispensable SKU for modern vehicle maintenance, offering global distributors a high-value, tech-integrated aftermarket solution.

Applications

Modern passenger vehicles equipped with Anti-lock Braking Systems (ABS).
Front and rear wheel hubs requiring sensor-integrated bearings.
Automotive electronic stability control (ESC) systems.

FAQ

Q: How do I know which side faces the ABS sensor?
A: The side with the magnetic encoder (often dark brown or black magnetic material on the seal) MUST face inward toward the vehicle's ABS sensor. A magnetic test card can be used to identify the correct side.
Q: Can a non-ABS bearing be used instead?
A: No. Using a standard bearing without the magnetic encoder will immediately trigger an ABS fault light and disable the anti-lock braking function.

OEM & Custom Service

B2B services include rigorous magnetic flux testing before shipment, customized packaging with clear installation warnings (ABS side indicator), and full aftermarket branding.

Packing & Delivery

Carefully packaged in individual boxes with protective inserts to prevent damage to the magnetic encoder, consolidated into heavy-duty export crates.
