Spline Rear Wheel Hub

Introducing Our Precision-Engineered Spline Rear Wheel Hub For high-performance racing applications where every component must deliver maximum reliability and power transfer, our Spline Rear Wheel Hub is engineered to meet the most demanding standards. As a critical connection point between the axle and the wheel, a robust Wheel Hub is non-negotiable. Our design is particularly favored in sprint car racing, where it serves as a premier Sprint Car Rear Wheel Hub, providing the torsional strength needed to handle immense torque loads. The innovative spline interface ensures a perfect, zero-play connection, directly driving the wheel without the slippage often associated with traditional bolt patterns. This hub is compatible with various wheel mounting styles and is an excellent foundation for both custom and standard Spoke Hub assemblies. Furthermore, its adaptability makes it a superior choice as a Wheel Center for Micro Sprint vehicles, offering scalability and performance across different racing classes. Built from aerospace-grade materials and subjected to rigorous testing, this hub is the cornerstone of a winning drivetrain.
The Spline Rear Wheel Hub is manufactured using a proprietary 4140 chromoly steel forging process, followed by precision CNC machining to achieve tolerances within ±0.0005 inches. This ensures an exact fit with matching splined axles, eliminating stress concentrations and promoting even load distribution. Each hub undergoes a multi-stage heat treatment, including carburizing and tempering, to achieve an optimal balance of a hardened, wear-resistant surface and a tough, shock-absorbing core. The flange is drilled with a universal 8-bolt pattern, accommodating most standard racing wheels, and is meticulously balanced to minimize rotational vibration. Critical dimensions, such as the pilot diameter and register, are held to stringent specifications to guarantee perfect wheel alignment and concentricity, which is vital for consistent handling and bearing life.

    Sheet Metal Laser Cutting Service

    We are experts in the field of Youlin® Sheet Metal Laser Cutting Service. Sheet metal laser cutting is one of metal profiling processes. It directs a high-powered laser through optics to cut materials for industrial applications. Laser cutting is both more precise and less energy-consuming than plasma cutting, but has an upper threshold on the thickness of the material being cut. Youlin offers both fiber and CO2 lasers that can cut many materials including mild steel, stainless steel, aluminum, copper, brass, and exotic alloys. CO2 (carbon dioxide) laser excels at cutting, engraving, and boring metals, while fiber laser is a good option for thicker materials.
