BiSlide® Free Motion Linear Stage
The simplest BiSlide® assembly where the slider is moved by hand.
The Velmex BiSlide® positioning stage’s modular design makes it highly configurable for a multitude of different motion-control applications. The manual BiSlide® 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; BiSlides deliver higher rigidity for longer life and more precise movement. BiSlides have a load capacity of 300 lbs. (136 kg.) horizontally and 100 lbs. (45.4 kg.) vertically. 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 the need arises. One, two and three axis systems are created by simply bolting together standard components utilizing the advantages of T-slot framing.
Features
Maximum load capacity – 300 lbs. (136.1 kg.)
Maximum Travel Distance – 80″ (203.2 cm)
Specifications
Factors such as size of the motor, size of the payload, travel distance, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.

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).

Options/Accessories for Free Motion Velmex BiSlides®
Several options can be added to BiSlide® Assemblies to make them more versatile and configurable with other Velmex products.
Velmex offers a multitude of options and accessories for all its products. Usually an option or an accessory will address your requirements. When it doesn’t, we can make custom modifications, including:
• Additional holes or slots. (A drawing is required.)
• Intermediate plates to mount your payload
• Special or in between lengths of the dovetail base
• Lead screw shaft extensions
• Choice of drive nut materials, including brass and Vespel
• Right and left-hand threads on the same lead screw, allowing a pair of sliders to move together or apart.
We can also offer customized configurations to address special environmental and vacuum applications.
Applications and Examples
Note: the example displayed may be a custom configuration, designed to the customer’s specifications; and not offered as a standard product. Custom configurations could contain custom, externally-fabricated components.
