Why EnduraSet
EnduraSet - An End of Manual Adjustment

The pre-adjusted design simplifies the installation process, allowing for quick mounting without additional adjustments, which minimizes downtime and enhances operational efficiency. EnduraSet assemblies also feature optimized bearing adjustments to reduce premature wear, resulting in lower maintenance costs and improved resource allocation for fleet operators. Advanced sealing technology protects against contaminants, further extending service life.

600,000 Mile Warranty

EnduraSet pre-adjusted assemblies provide a range of benefits for fleet owners and axle assembly shops, highlighted by an impressive 600,000-mile lifespan. This exceptional durability ensures long-term reliability, significantly reducing replacement frequency and associated costs. Engineered for strength, these assemblies withstand extreme operating conditions, making them ideal for heavy-duty applications.

Superior Trailer Hubs, Engineered Around Our High-Performance Wheel Bearings

While the trailer's frame is the foundation of the suspension, the wheel hub is the heart of the wheel-end assembly. As a leading wheel hub manufacturer, we design and produce complete trailer hub solutions that leverage the quality and durability of our core product. Our hubs deliver optimal performance, safety, and longevity for trailers carrying everything from light goods to heavy equipment.

Built For Reliability, Centered on Our Hubs

Our trailer hubs are more than just a steel component—they are a high-quality system engineered around a critical function: robust, precise wheel rotation.

  • Integrated Design: Every aspect of our hub assembly, from the wheel bearings to the seals, is designed to work in perfect harmony with our precision-engineered casting.
  • Optimal Load Distribution: The hub acts as the core interface between the wheel and the spindle, ensuring the weight is distributed evenly across the bearings. This prevents premature wear and fatigue, even under demanding conditions.
  • Enhanced Performance: The superior quality of our hubs and bearings minimizes friction and heat buildup. This results in smoother, more reliable wheel rotation and a more efficient towing experience.

Features

Pre-Adjusted Bearings

Pre-adjusted bearings are designed with factory-optimized settings that ensure the ideal preload and end-play, removing the need for manual adjustments during installation. This precision setup leads to extended hub life and reliable performance, reducing maintenance needs and operational downtime. The consistent preload on the bearings helps in distributing the load evenly, enhancing the efficiency of the wheel hub assembly and improving vehicle safety.

Precision-Ground Spacer

A precision-ground spacer is included between the inboard and outboard bearings to ensure an exact dimensional adjustment. This spacer is engineered to maintain a consistent and precise fit, promoting even bearing loading and preventing premature wear. Its role in maintaining dimensional accuracy contributes to the overall balance and alignment of the wheel hub, ensuring the vehicle runs smoothly and reducing the risk of bearing failure.

Robust Sealing System

The robust sealing system is a four-zone labyrinth configuration that effectively prevents external contaminants such as dust, water, and debris from entering the wheel hub. Simultaneously, it ensures that lubricant stays sealed within the system, maintaining the integrity of the bearings. By minimizing exposure to harmful elements and retaining optimal lubrication, this sealing system enhances the longevity of the hub assembly and ensures smoother performance even in harsh environmental conditions.

Durable ABS Tone Ring

The ABS (Anti-lock Braking System) tone ring, machined from corrosion-resistant ductile iron, is built for durability and reliable performance in demanding conditions. Its construction ensures it withstands environmental challenges like moisture and corrosion, contributing to long-lasting service. The tone ring works seamlessly with the ABS system, providing accurate data on wheel speed and helping prevent wheel lockup during braking, enhancing vehicle control and safety.
