Heavy Duty Steel Ball Spline Model LT With Double Nut Cylindrical Medium Torque Shaft 5mm Diameter By 130mm Length Nut 12mm Diameter By 20mm Length Radial Load 198 Lb High Precision Linear Motion Component For Industrial Apps

Heavy Duty Steel Ball Spline LT with Double Nut 5mm x 130mm
✔️ Single unit, 5 mm shaft, 12x20 mm nut, 130 mm long, 198 lb load

The Ball Spline is a high-precision linear motion component that uses balls housed in the spline nut to transmit torque along precision-ground raceways on the shaft. With preload on the crests, it delivers high rigidity in both radial and torque directions, making it ideal for industrial machinery, automated systems, and precision positioning setups where vibrations and impact loads are common.

✅ High radial load rating: 198 lb
✅ Shaft diameter: 5 mm
✅ Nut diameter: 12 mm, nut length 20 mm
✅ Shaft length: 130 mm

💡 What is a ball spline used for in precision motion systems? This handy guide explains the basics.
- Ball spline transmits torque via rolling elements while guiding linear motion
- It uses preload to improve stiffness and positioning accuracy under vibration
- Commonly used in automation, CNC, robotics for precise, smooth motion
