ULTR-A Series is the lightweight version of the UVT ball spline family, designed for applications where reducing moving mass improves speed, acceleration and energy efficiency. The optimized outer cylinder keeps rigidity while lowering weight, ideal for high-speed pick-and-place and robot end-effectors.
Key features:
Lightweight outer cylinder for lower inertia and higher acceleration
High rigidity 4-point contact design retained
Smooth, quiet linear motion with torque transmission
Infinite stroke standard; limited stroke and flange options available
Reduced energy consumption in high-cycle machines
Typical applications: high-speed pick-and-place heads, gantry robots, semiconductor handling, packaging machines and any mechanism where moving mass directly limits cycle time.
