Manually-Operated UniSlide® A15 Series



The smallest of the UniSlide Linear Stages with a body width of 1.5 inches, slider length of 1.5 inches and a carrying capacity of 15 lbs. horizontal load. The A15 can travel up to 25.5" with the 1.5" slider/carriage. Because of it's light weight, the A15 Series is ideal for moving small sensors.

A15 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. A15 lead screws are constrained and supported with pre-loaded Delrin® thrust bearings, which have pre-loaded ball bearings. The lead screw drive nut is a tension adjustable nut made of Delrin providing low friction, and minimal backlash.

The A15 Series UniSlide is available in 8 styles. Four 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 A15 Series Assemblies include:

Free Sliding A15  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 several different diameter lead screws available for the A15 Series in 1/4" and 7 mm. Each have different advance ratings.

 UniSlide A15 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 A15 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 A15 UniSlide limited adjust

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

Rapid Advance UniSlide unlimited adjust

Rapid Advance with Scale and Vernier – The limited 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 A15 Series UniSlide - MA15 Series. Other configurations and sizes are available on the other Series UniSlide Assemblies - A25, A40, 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.

Options/Accessories

An array of options and accessories is available for the A15 Series UniSlide Assemblies

Adapter Plates

XY Plates – allow two UniSlides to be converted into an XY motion system. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XY Adapter Plate

A1500XY Adapter Plate – To mount two A15 Series UniSlide in XY.

XZ Plates – Allow UniSlide assemblies to be positioned vertically facing in any of four directions. For more specifics and to see the adapter plates in use on a Velmex stage visit the UniSlide Adapters page.

A1500XZ XZ Adapter Plate

A1500XZ Adapter Plate– To mount an A15 Series UniSlide to another A15 Series in XZ.

XZ Brackets – allow UniSlide assemblies to be positioned vertically, facing in any of four directions and perpendicular to the X or Y plane. For more specifics and to see the brackets in use on a Velmex stage visit the UniSlide Adapters page.

XZ Adapter Brackets - A25 Series

A2501XZ Adapter Bracket – To mount an A25 Series UniSlide to another A25 Series (6"- 9") or to an A15 Series (6"- 9") in XZ. (The A25 would be the base horizontal stage. The other stage would be mounted vertically.)

For more specifics and to see the shelf in use on a Velmex stage visit the UniSlide Adapters page.

UniSlides with two different size sliders

Slider Lengths – Varying length carriages (sliders) can be added to all models of UniSlide Assemblies. Choosing a longer slider reduces the standard travel distance. 1.5" is the standard slider on the A15 Series. Optional lengths available for the A15 are 2" or 3".

Variety of Knobs for UniSlides

Alternative Knobs – A variety of knob styles can be substitute for the standard knob available on the particular style/model of UniSlide Assembly.

 

• Small diameter (5/8") Rogan knob for some A15, A25, A40 Models and Turntables
• Knobs with cranks including:
    – Plain knob (1 3/4" diameter)
    – Drum dial
    – Engraved knob 1 3/4" diameter)
• Reduced diameter graduated knobs for A15 Graduate Knob models

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.

Way covers on UniSlides

Wrench - Retainer Nut – Velmex has a custom-designed wrench to easily adjust and remove the threaded retainer nut on UniSlides. When needed, this makes removing and changing the lead screw simple and easy. The wrench is designed for the smaller diameter lead screws (1/4" or 7 mm - A15 Series and some A25) with the split Delrin® thrust bearings and the threaded retainer nut. Note: larger diameter lead screws (3/8", 1/2", 10 mm and 14 mm) use steel bearings and a snap ring retainer.

Black Anodized UniSlide

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
