What Is a Ball Spline? Structure, Working Principle and Uses
A ball spline transmits torque while allowing smooth linear motion. Here is how it works and where it beats a keyed shaft.
ReadTechnical NoteHow to Select a Miniature Ball Spline in 5 Steps
Shaft diameter, load, speed, stroke and preload — a practical checklist for design engineers.
ReadTechnical NoteBall Spline vs Linear Bushing: Which One Do You Need?
Both guide linear motion. Only one carries torque. Compare load, rigidity, accuracy and cost.
