Description

Basic Parameters

The DAC30500020 designed for automotive wheel hub applications, featuring a 30mm inner diameter, 50mm outer diameter, and 20mm width. Engineered to support both radial and axial loads typical in wheel assemblies, this bearing ensures smooth rotation of the hub while maintaining structural integrity under vehicle weight. Its compact single-row configuration aligns with standard hub bearing requirements, offering pre-assembled reliability without the need for on-site clearance adjustments—a key advantage over traditional tapered roller setups. Commonly integrated into passenger car wheel systems, the DAC30500020 balances load capacity and precision, making it suitable for front or rear hub installations where space efficiency and durable performance are critical.

 

Product Application

The DAC30500020 Wheel Hub Ball Bearing is a high-precision, durable component engineered for versatile automotive wheel hub systems, specifically tailored for passenger cars, compact SUVs, and light commercial vehicles. Its standardized dimensions (30mm inner diameter, 50mm outer diameter, 20mm width) make it compatible with a wide range of front and rear axle configurations, particularly in models requiring space-efficient, maintenance-friendly solutions.

1. Primary Vehicle Compatibility

Designed as a single-row deep groove ball bearing, it excels in applications where balanced radial and axial load resistance is critical, such as non-driven wheel hubs (e.g., rear wheels in front-wheel-drive vehicles or front wheels in rear-wheel-drive setups). It integrates seamlessly with common hub assemblies featuring bolt-on brake discs or drums, and works harmoniously with anti-lock braking system (ABS) sensors when paired with optional encoder rings (available in variant models). This makes it an ideal choice for OEM manufacturers and aftermarket replacement sectors targeting mid-to-high-volume vehicle platforms.

2. Performance in Diverse Operating Conditions

The bearing’s robust steel construction (typically made from high-carbon chromium steel, heat-treated for optimal hardness and fatigue resistance) ensures reliable performance across extreme temperature ranges (-40°C to +120°C) and harsh environments. Its precision-ground raceways and optimized ball geometry reduce rotational friction, enhancing fuel efficiency while minimizing noise, vibration, and harshness (NVH). In urban driving scenarios with frequent stops/starts, the bearing’s low torque design and pre-lubricated sealed structure (using double-lip rubber seals to prevent dust, water, and debris ingress) maintain consistent performance without compromising on service life. For highway applications, it stabilizes high-speed rotations (up to 180 km/h) with minimal radial runout, ensuring steering precision and passenger comfort.

3. Installation and Maintenance Advantages

The DAC30500020 simplifies assembly processes with its pre-adjusted internal clearance and press-fit design, eliminating the need for on-site manual adjustment—a key benefit for both professional mechanics and DIY enthusiasts. Its unitized structure integrates the inner ring, outer ring, ball set, and seals as a single module, reducing installation time by up to 30% compared to traditional split-type bearings. The permanent grease filling (using high-temperature-resistant lithium-based grease) ensures lifelong lubrication, eliminating periodic maintenance requirements and extending service intervals to over 150,000 kilometers under normal operating conditions.

4. Safety and Industry Compliance

Compliant with international standards such as ISO 681 and ABE (Automotive Bearing Engineering) guidelines, this bearing undergoes rigorous testing for load capacity (static load rating: 22 kN, dynamic load rating: 18 kN) and fatigue endurance, ensuring compliance with safety-critical automotive regulations. Its design also incorporates anti-corrosion surface treatments (e.g., zinc-nickel plating) to withstand salt-spray environments, making it suitable for vehicles operated in coastal regions or areas with winter road de-icing practices.

5. Aftermarket and Customization Potential

In the aftermarket, the DAC30500020 serves as a direct replacement for obsolete bearing part numbers, offering cross-compatibility with legacy hub systems while delivering modern performance upgrades. For OEM clients, minor design modifications (e.g., customized seal profiles or material coatings) can be accommodated to meet specific vehicle dynamics requirements, ensuring seamless integration into next-generation lightweight hub designs focused on reducing unsprung mass and enhancing overall vehicle efficiency.
