UniSlide® A40 Series



The A40 Series UniSlide stage has a body width of 4 inches, slider length of 4 inches carrying a 100 lbs. horizontal load. The A40 can travel up to 38" with the 4" slider/carriage. The A40 is very versatile for a variety of applications.

A40 Series UniSlides are comprised of an aluminum alloy extruded dovetail base with 60 degree opposing V-type ways. An aluminum alloy carriage that runs in the dovetail ways of the base. Lead screws are constrained and supported with steel thrust bearings and snap ring retainer. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.

The A40 Series UniSlide is available in 10 models/styles. Seven lead screw pitches are available along with rapid advance configurations.


Linear UniSlide Assembly Style/Model Options

The UniSlide Series and the styles below combine to create a complete UniSlide Assembly model. Additional options and accessories can be added (See Options/Accessories). Standard style/model options for UniSlide A40 Series Assemblies include:

Free Sliding A40  UniSlide

Free Sliding Model – The simplest UniSlide Assembly where the slider is moved by hand. This features a linear dovetail bearing for smooth motion.

Screw Drive UniSlide

Screw Drive Models – Slide movement is controlled by a lead screw. There are a variety of different diameter lead screws available from 3/8" to 1/2" and 10 mm. Each have different advance ratings.

 UniSlide A40 with Graduate Knob

Graduated Knob Models – The position of the payload is measured by combining the readings from the linear scale and engraved knob or drum dial. Measures position from 0.0001" or 0.01 mm.

 UniSlide A40 with Scale and Vernier

Scale and Vernier Screw Drive Models – Includes a precision English or Metric scale on the base and offset vernier on the slider. Measures position from 0.001" or 0.05 mm.

Rapid Advance Models – Are for quickly repositioning the slider by uncoupling the drive system. This saves time when the slider will be moved frequently or when the base length is long. Each have varying lengths of fine adjustment. The limited fine adjust models use a clamping-like drive. The unlimited fine adjust models use a lead screw and pinion design. Rapid Advance models are not recommended for vertical (Z axis) mounting.

Rapid Advance A40 UniSlide limited adjust

Rapid Advance with Limited Fine Adjust – Have 1/2" of fine pitch adjustment control.

Rapid Advance UniSlide limited adjust and scale and vernier

Rapid Advance with Limited Fine Adjust with Scale and Vernier – Limited fine adjust is also available with an English or Metric scale and vernier.

Rapid Advance A40 UniSlide unlimited adjust

Rapid Advance with Unlimited Fine Adjust – Can be finely adjusted along the full length of the travel. Load is limited to 50 pounds horizontal or 2 pounds vertical. Configuration available on A25, A40 and A60 Series.

Rapid Advance UniSlide unlimited adjust and scale and vernier

Rapid Advance with Unlimited Fine Adjust with Scale and Vernier – The unlimited fine adjust is also available with an English or Metric scale and vernier.

Rapid Advance UniSlide with Micrometer

Rapid Advance with Micrometer Head – The limited fine adjustment is made with a micrometer calibrated to 0.001" or 0.01 mm. Configuration available on A15, A25 and A40 Series.

Left-Right A15  UniSlide Assembly

Left-Right Screw Drive Models – Use two carriages (sliders) and have a common lead screw machined with a left thread on one half and a right thread on the other half. The slides simultaneously move toward or away from each other. Use for applications where two objects must share a common axis of movement. Dual Screw models also available with two screws contolled independently with two knobs.

 

There is a motorized version of the A40 Series UniSlide - MA40 Series. Other configurations and sizes are available on the other Series UniSlide Assemblies - A15, A25, A60, B90.


UniSlide Configurations

The basic linear UniSlide is a 1-axis stage. UniSlides can be combined for multiple axes in a wide range of lengths and payload capacities. See Examples for images of various multi-axis UniSlides and combinations that include other Velmex stages.

Locks – There are a number ways to lock the carriage (slider) position on UniSlides. They include:

Thumb lock on lead screw

Thumbscrew-on-Lead-Screw Lock (-TL) – An easy method to fix the slider utilizing a simple thumbscrew. The thumbscrew lock increases the overall length of the UniSlide base. This lock type is not available on Rapid Advance models.

Travelling Slider Lock

Traveling Slider Lock (-TSL) – This lock attaches to the slider to lock the carriage in place. Available on Free Sliding, Screw Motion and Graduated Knob models only.

Slider Lock

Slider Lock (-SLR or -SLL) – This lock is mounted at the mid-point on the base and is tightened to prevent slider movement. This is only available on slides where the carriage (slide) length is greater than one-half the base length. It can be mounted on the right (-SLR) or left (-SLL) of the base.

Revolution Counter

Revolution Counter (-RC) – A mechanical revolution counter provides a convenient 1/10 revolution increment count. Readouts in either 0.01" or 0.1 mm. Counts precisely with 0.100" or 1 mm lead screws. Other screws require additional calculations. For details see UniSlide Counter page.

Left Right Screw Motion

Left-Right Screw Motion (-LR) – This configuration is very useful for applications where two objects must share a common axis of movement. This assembly incorporates two carriages driven by a single right- and left-hand threaded lead screw. When the knob is turned, the carriages simultaneously move toward or away from each other.

Independent Left-Right Slider UniSlide

Two Independent Carriages (-DS) – a variation on the left-right screw motion UniSlide is one containing two lead screws with control knobs at both ends of the assembly. Each lead screw and carriage operates independently.

Right angle gear box on UniSlide

Right Angle Gearbox – Allows the control knob or wheel to be offset perpendicular to the UniSlide ways. Ideal for tight spaces or applications where access to the end of the stage is limited. Available on A25, A40, A60 and B90 Series.

For more specifics on the gearbox visit the UniSlide Adapters page.

Way covers on UniSlides

Way Covers (-WC) – Protect the slider and dovetail base from dust, dirt and grit that could hamper the efficient operation of the slide. Way covers increase slider height and reduce the travel length of linear UniSlide stages. Not available on Series A15 Assemblies. Available on free sliding, screw drive and graduated knob models of the other assemblies.

Black Anodized XY A40 UniSlides

Finishes – Standard UniSlide Assemblies have a brushed aluminum finish. Optional finishes are available at an additional charge and include:

 

• Black Anodizing, additional colors also available. (pictured)
• Hard Coat Anodized and dyed black
• Electroless Nickel Plated
• Specialized coatings for specific applications such as food processing or medical applications
• Modifications for use in a vacuum environment

VRO with an UniSlide Assembly

Encoders and VRO® Encoder Readout For a high resolution position readout an encoder and Velmex's VRO encoder readout can be mounted to most linear UniSlide assemblies. An encoder, mounted directly to the slider gives a true and accurate reading eliminating lead screw and backlash errors. (Not available on all UniSlide models.) SEE: Velmex Controls on the Encoders and the VRO Readout for additional details.
