Manual BiSlide® Linear Stage
BiSlide® Manual Lead Screw Stages offer precise, smooth linear motion with durable construction—ideal for lab, OEM, and positioning applications.
The modular design of Velmex BiSlide® positioning stages make it highly configurable for a multitude of different motion-control applications. The manual BiSlide® Knob and Screw assembly is available in a choice of linear travel distances up to 80 inches.
Constructed with hard-coat anodized, aluminum dovetail ways and smooth motion PTFE bearings; BiSlide® assemblies deliver higher rigidity for longer life and more precise movement. Rapid Advance BiSlide® Assemblies have a load capacity of 150 lbs. (68.04 kg.) horizontally. Straight-line accuracy is 0.003″ (0.076 mm) over entire travel distance. Repeatability is 0.0002 inch (0.005 mm).
Because BiSlide® components are interchangeable, they can easily be reconfigured as future needs arise. One, two and three axis systems are created by simply bolting together standard components utilizing the advantages of T-slot framing.

BiSlide® Load Calculations
Note:
Because of the interlocking nature of the BiSlide® carriage and the dovetail ways, the maximum recommended load centered (normal) or under thrust would be comparable whether the slide was upright (Normal – LN), Inverted (LI) or set on the Edge (LE).
To calculate equivalent center load for a cantilevered load: Lc = (Dx L/2) + L
