Ball Screw Spline Unit USLT - Limited Stroke

USLT Series - Miniature Limited Stroke Ball Spline

USLT Series is a miniature limited-stroke ball spline developed for small-space, high-frequency reciprocation. Compact outer cylinder with a short spline path keeps the assembly short while maintaining the rigidity required for precision mechanisms.

Key features:

• Limited stroke design for short-stroke, high-frequency motion

• Miniature dimensions - suitable for Φ3mm-class ultra-small shafts

• 4-point contact balls for high rigidity in a small package

• Optimized for high-speed reciprocation with low heat generation

• Stainless steel options for clean-room environments

Typical applications: SMT mounter nozzle shafts, semiconductor packaging, IC test equipment, small pick-and-place heads and medical instruments.

UVT is one of only two manufacturers worldwide capable of stable Φ3mm ultra-precision miniature ball splines - ask us for details.
