Product Overview

DAC Series Wheel Hub Bearings (Double Row Angular Contact Ball Bearings for Automotive Wheels) are integrated dual-row precision units engineered to support heavy radial and bidirectional axial loads in vehicle wheel assemblies. Featuring a unified outer ring and two inner rings with pre-adjusted internal clearance, the DAC series simplifies wheel hub assembly by eliminating the need for manual preload adjustments during installation. Manufactured from high-purity GCr15 Chrome Steel or premium case-carburized alloy steel, these bearings are equipped with high-performance multi-lip seals and heat-resistant synthetic grease. DAC series bearings are widely specified in passenger cars, light commercial vehicles, and SUVs across front and rear wheel hub assemblies.

Key Features & Advantages

Integrated Double-Row Construction: Compact dual-row angular contact structure accommodates simultaneous high radial forces and heavy axial cornering loads.

Pre-Adjusted Factory Clearance: Preset internal axial clearance eliminates complicated setting procedures during vehicle assembly, reducing installation time and human error.

Superior Sealing Protection: High-integrity multi-lip rubber contact seals (2RS / ABS encoder integrated) block road water, dust, and de-icing salt while retaining internal lubricant.

High Rigidity & Angular Stability: Optimized contact angle geometry provides high structural stiffness, resisting wheel deflection and improving dynamic handling safety.

Optional ABS Magnetic Encoder: Available with integrated ABS sensor rings or magnetic tone wheels on the seal face to deliver accurate wheel speed signals to vehicle stability systems.
