ULTR-B weight type

ULTR-B Series - Weight-Optimized Heavy-Duty Ball Spline

ULTR-B Series is the weight-optimized heavy-duty ball spline from UVT, balancing load capacity and moving mass for demanding high-speed applications. It keeps the rigidity needed for precision positioning while reducing inertia for faster acceleration.

Key features:

• Optimized weight-to-rigidity ratio for high dynamic performance

• High load capacity with 4-point contact ball design

• Suitable for continuous high-frequency operation

• Multiple mounting styles available (infinite stroke standard)

• Long-life design validated under working-condition testing

Typical applications: high-speed gantries, robot axes, SMT equipment and automated production systems where speed and precision both matter.
