Ball Splines
Thomson ball splines, which enable rotary and linear motion on a single shaft, deliver high reliability and life expectancy under varying operating conditions. Ball splines are optimal for applications that require high speed, vibration, shock loading, precise positioning requirements and high torsional loads.
Keep your Design Project on Time and Budget
When you order Thomson precision ball splines that include machined ends, you will never need to worry about additional time or costs. Whether it's coaxial holes, external threads, single- or two-step reduction or ring grooves, our end machining options come standard and require no extra design time* or expense.
* For ten (10) or fewer Thomson precision ball splines, end machining will be completed in three (3) business days.

Packaging
Thomson precision ball splines simplify XYZ movement into linear and rotary motion, thereby reducing the number of parts and complexity required for picking up an item and placing it in another location. Fewer components and simpler designs result in lower costs, higher efficiencies, less maintenance and quicker lead times.
Robotics
Faster movement and accurate positioning result in significant reductions in production time, which is critical for mass machining environments. Thomson precision ball splines simplify these systems by providing both linear and rotary motion on one shaft. Their robust capacity supplies a reliable option for tool holding in robotic applications such as CNC machining.
Rotating Drum for Paper Mill
The high load capacity of Thomson precision ball splines provides the required rigidity when they are challenged by heavy objects. In addition, the nut design helps lock the rotational movement when the application is at rest.
Machine Automation
The accuracy of Thomson precision ball splines makes them ideal for many machine automation applications. For example, on a honing machine, precision is critical in maintaining a steady combination of rotary and linear motion.
