Steel Ball Spline Model LT Double Nut Cylindrical High Load Linear Motion System With 5mm Diameter Shaft By 70mm Length And 12mm Diameter Nut By 20mm Length 198 Lb Radial Load Capacity For Medium Torque Applications

High-Load Steel Ball Spline LT Double Nut Linear Drive
✔️ 5 mm shaft, 70 mm length; 12 mm nut, 20 mm; 198 lb radial load; Pack: 1

The ball spline is a high-load linear motion element that transmits torque through rolling balls between a cylindrical shaft and a nut. This Model LT is designed for heavy-duty positioning in automation, robotics, and CNC guides where precise motion and high rigidity matter.

✅ 5 mm shaft diameter, 70 mm length
✅ 12 mm nut diameter, 20 mm length
✅ 198 lb radial load capacity
✅ Model LT type for medium torque tasks
✅ Double nut with preload on crests for rigidity

💡 What is a ball spline and why should I use it for precise linear motion?

Ball splines transfer torque through rolling elements while guiding linear travel, delivering stiffness and smooth motion.

• handy for accurate positioning in automation and robotics
• preload on crest balls improves stiffness and reduces backlash
• handles vibration and sudden loads better than basic bearings
• offers long service life in challenging industrial setups
