MA40 Series UniSlide

Motor-Driven UniSlide® MA40 Series


The MA40 Series UniSlide stage has a body width of 4 inches, slider length of 4 inches carrying a 100 lbs. horizontal load. The MA40 can travel up to 31" with the 4" slider/carriage. The MA40 Series UniSlide is available in 7 lead screw pitches. Recommended step rate is 1000/steps per second. The MA40 is versatile for a variety of applications.

MA40 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 MA40 Series is part of 5 motorized UniSlide Series. Others are MA15, MA25, MA60, MB90. There is also a manual version - the A40 Series.

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.

UniSlide Configurations

 

Options/Accessories

A4000XY Adapter Plate – To mount a MA40 Series UniSlide to another AM40 Series or to a MA25 Series in XY. (The MA40 would be the base stage.)

A6000XY Adapter Plates

A6000XY Adapter Plate – To mount a MA60 Series UniSlide to another MA60 Series or to a MA40 Series in XY. (The MA60 would be the base stage.)

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.

A4000XZ Adapter Plates

A4000XZ Adapter Plate – To mount a MA40 Series UniSlide or a MA25 Series vertically to another MA40 Series in XZ. (The MA40 would be the base horizontal stage.)

A6000XZ Adapter Plates

A6000XZ Adapter Plate – To mount a MA60 Series UniSlide to another MA60 Series or to a MA40 Series in XZ. (The A60 would be the base horizontal stage.)

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 - A40 Series

A4001XZ Adapter Bracket – To mount a MA40 Series UniSlide (6"- 9") or a MA25 Series (6"- 9") vertically to another MA40 Series in XZ. (The MA40 would be the upper horizontal stage.) Can also mount two B4800TS Rotary Tables at right angles.
B4003XZ Adapter Bracket –To mount a MA40 Series UniSlide to another MA40 Series (12"- 15") or to a MA25 Series (12"- 15") in XZ. (The MA40 would be the base horizontal stage.)
B4004XZ Adapter Bracket – To mount a MA40 Series UniSlide to another MA40 Series (over 15") or to a MA25 Series (over 15") in XZ. (The MA40 would be the base horizontal stage.)

XZ Adapter Brackets - A60 Series

A6001XZ Adapter Bracket– To mount a MA60 Series UniSlide to another MA60 Series (up to 12") or to a MA40 Series (up to 12") in XZ. (The MA60 would be the base horizontal stage.)
B6003XZ Adapter Bracket – To mount a MA60 Series UniSlide to another MA60 Series (12"- 15") or to a MA40 Series (12"- 15") in XZ. (The MA60 would be the base horizontal stage.)

Platform Shelves

Platform Shelf – A right angled bracket designed to be used with UniSlide® Elevating Tables. However, they also can be used with vertically mounted UniSlide Assemblies to support a payload. The shelf can be inverted depending on the motion required.

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. 4" is the standard slider on the A40 Series. 6" is the optional length available for the A40.

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.

Fixed Limit Switches on UniSlide

Limit Switches – Outboard adjustable and fixed end-of-travel limit switches are available as an option.

 

Outboard Adjustable Limit Switches – Mounted on the side rib of Velmex UniSlide Assemblies, these switches can be used to stop travel, provide more stops than the standard two, over-travel a stop point, change speed or be active in only one direction. (pictured)

Fixed, End-of-travel Limit Switches – These push button switches are fixed on the end plate of Velmex Unislide Assemblies. They are not adjustable.

See Limits for more information.

Way covers on motorized 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 Motorized Series MA15 Assemblies.

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

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.

Double Shaft Motor with Control Knob

Motorized / Manual OperationIt is possible, using a double shaft motor, to produce a Velmex stage that can be manually operated or motor-driven. A shaft extension accommodates the either a Rogan or standard aluminum knob.

The motor is purchased separately. Customers can mount their own motors, if they chose.

Stepper Motor

Motors A variety of motors are available to power Velmex UniSlides, most popular of which is the DC step motor. Gear motors, servo motors and high resolution step motors in both AC and DC can run Velmex UniSlides. SEE: Velmex Controls on the Motors for additional details.

The motor is purchased separately. Customers can mount their own motors, if they chose.

UniSlide with a VXM Controller

VXM™ Controller Step motors coupled with a motor controller like the Velmex VXM are a cost effective solution for accurate speed and precise incremental positioning. SEE: Velmex Controls on the VXM Controller for additional details.

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
