The DAC 30mm Series encompasses a highly popular range of Generation 1 (Gen 1) auto wheel hub bearings, including the DAC30620044, DAC30630042, DAC30640042, and DAC30640037. Designed with a 30 mm internal bore, these double-row angular contact ball bearings provide exceptional rigidity to withstand both the vertical weight of the vehicle and the lateral thrust of cornering. Sealed for life and manufactured from premium GCr15 chrome steel, they are direct OEM replacements for a wide variety of passenger cars and light trucks. We supply global auto parts distributors with custom branding, flexible packaging, and competitive bulk pricing.
The DAC Series Wheel Hub Bearing is fundamentally designed to reduce friction and support the heavy dynamic loads of modern automotive drivetrains. Because they utilize a double-row angular contact structure, these bearings essentially combine two single-row bearings back-to-back into one highly compact outer ring. This unified design ensures that the internal clearance is perfectly pre-set at the factory, meaning automotive technicians do not need to perform complex clearance adjustments during installation, saving time and preventing mechanical failures.
The part numbers in the DAC series directly correspond to their exact physical dimensions (Inner Diameter x Outer Diameter x Width). Please use the chart below to ensure accurate fitment for your replacement kits.
Model Number | Inner Diameter (d) | Outer Diameter (D) | Width/Thickness (B) | Weight |
|---|---|---|---|---|
DAC30620044 | 30 mm | 62 mm | 44 mm | ≈ 0.50 kg |
DAC30630042 | 30 mm | 63 mm | 42 mm | ≈ 0.57 kg |
DAC30640037 | 30 mm | 64 mm | 37 mm | ≈ 0.48 kg |
DAC30640042 | 30 mm | 64 mm | 42 mm | ≈ 0.58 kg |
General Specifications:
Bearing Type: Double-Row Angular Contact Ball Bearing
Material: Premium Chrome Steel (GCr15 / SAE52100)
Seal Type: 2RS (Rubber shields on both sides for maximum protection)
Precision Rating: ABEC-1 / ABEC-3 (P0 / P6)
Our 30mm bore DAC series is engineered for the Independent Aftermarket (IAM), offering OEM-level reliability that prevents costly warranty returns:
Heavy Load Capacity: The bigger ball-filling angle and robust GCr15 steel construction allow these bearings to handle severe radial shocks and axial thrust forces simultaneously.
Sealed for Life: Pre-lubricated with high-temperature automotive grease and sealed with multi-lip rubber closures to block out mud, water, and brake dust entirely.
High-Speed Stability: Micro-polished raceways ensure noise-free rotation and low friction at high driving speeds.
These bearings are standard high-turnover items for auto repair chains, used in the front and rear wheel hubs of numerous passenger vehicles:
Compact and mid-size passenger sedans (e.g., specific models from Honda, Ford, Mercedes, and Nissan).
Light-duty trucks and SUVs.
Off-road ATVs and recreational utility vehicles.
We provide flexible, high-volume manufacturing solutions tailored to the needs of auto parts wholesalers and brand owners globally.
Custom Branding: We can laser-etch your company logo or specific OEM cross-reference numbers directly onto the bearing seals or steel rings.
Packaging: Supplied in neutral paper boxes for general distribution, or fully customized, full-color retail packaging to match your brand guidelines.
Lead Time & Payment: Fast dispatch for in-stock items (typically 3 days), with standard production runs completed within 20 days. We accept T/T, L/C, and Western Union.
