The TBI SLT13 13mm linear ball spline shaft with four-point contact design represents a significant advancement in load distribution and motion precision for demanding industrial applications. This innovative configuration doubles the contact points compared to conventional spline systems, creating superior load-bearing capacity while maintaining exceptional smoothness of movement. The unique geometry ensures constant, balanced pressure distribution across four precisely aligned contact surfaces, significantly enhancing rigidity and reducing stress on individual bearing elements. TBI's engineering expertise is evident in how this design maintains frictionless motion characteristics despite the increased contact area, achieving an optimal balance between durability and performance. The four-point contact system provides inherent stability that resists deflection under moment loads, making it ideal for applications requiring both precise linear guidance and rotational accuracy. Precision-ground raceways and carefully matched bearing elements work in perfect synchronization to deliver consistent performance throughout the shaft's service life. Designed for high-performance automation, precision robotics, and advanced machinery where motion quality directly impacts results, this spline shaft demonstrates TBI's ability to push the boundaries of motion technology. The SLT13 series offers system designers a robust solution that combines the benefits of enhanced load capacity with the smooth, precise movement characteristic of premium ball spline systems, creating new possibilities for applications where both extreme durability and flawless motion quality are essential requirements.
