Product Introduction

ULF Series - Flange Type Ball Spline for Compact Mounting

ULF Series is the flange-mounting ball spline from UVT, combining the high rigidity of 4-point contact balls with a flange outer cylinder for direct, stable mounting. It simplifies assembly, shortens installation time and is well suited to compact equipment modules.

Key features:

  • Flange type outer cylinder with bolted mounting holes

  • 4-point contact ball spline for high load capacity

  • Stable accuracy and interchangeability across batches

  • Available in multiple shaft diameters with custom end machining

  • Ideal for high-frequency reciprocation with consistent positioning

Typical applications: SMT mounters, component inserters, automated assembly modules, medical equipment and robotics.
