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.
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.
Available with flanged or non-flanged nuts, these ball splines meet the needs of high-precision, multi-axis motion applications.
Product SelectorAvailable with or without keyways, these ball splines offer high speed, anti-friction linear motion under high torsional loads.
Product SelectorThomson ball splines enable rotary and linear motion on a single shaft, offering versatility to a number of industrial applications.
Delivering high reliability and life expectancy under varying operating conditions, Thomson ball splines are optimal for applications that require high speed, vibration, shock loading, precise positioning requirements and high torsional loads.
Not every linear motion design can meet the optimal specifications by using standard ball splines. In these cases, Thomson offers its engineering services to help you customize ball splines to meet your exact requirements and keep your project running smoothly.
Thomson provides extensive online resources to help you no matter where you may be in the purchase decision process:
To further optimize performance and extend the lifespan of precision ball splines in various environments, three different coating options are available. Learn the benefits each coating provides in this video.
