MA40 Series UniSlide

Motor-Driven UniSlide® MB90 Series


The MB90 Series UniSlide stage has a body width of 9 inches, slider length of 9 inches, carrying a 400 lbs. horizontal load. The MB90 can travel up to 36" with the 9" slider/carriage. The MB90 Series UniSlide is available in 7 lead screw pitches. Recommended step rate is 1000/steps per second. The MB90 is ideal where a heavy-duty workhorse is required..

MB90 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 MB90 Series is part of 5 motorized UniSlide Series. Others are MA15, MA25, MA40, MA60. There is also a manual version - the B90 Series.

 

 
UniSlide Specifications – Motor-Driven Assemblies

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.

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

An array of options and accessories is available for the MA15 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.

B9000XY Adapter Plate

B9000XY Adapter Plate – To mount a MB90 Series UniSlide to another MB90 Series or to a MA60 Series in XY. (The MB90 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.

B9000XZ Adapter Plate

B9000XZ Adapter Plate – To mount a MB90 Series UniSlide to another MB90 Series or to a MA60 Series in XZ. (The MB90 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 - B90 Series

B9001XZ Adapter Bracket – To mount a MB90 Series UniSlide to another MB90 Series (up to 18") or to a MA60 Series (up to 18") in XZ. (The MB90 would be the base horizontal stage.)
B9002XZ Adapter Bracket – To mount a MB90 Series UniSlide to another MB90 Series (21"- 24") or to a MA60 Series (21"- 24") in XZ. (TheM B90 would be the base horizontal stage.)
B9003XZ Adapter Bracket – To mount a MB90 Series UniSlide to another MB90 Series (over 24") or to a MA60 Series (over 24") in XZ. (The MB90 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. 9" is the standard slider on the MB90 Series. 12" is the optional length available for the MB90.

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.

Fixed, End-of-travel Limit Switches – These push button switches are fixed on the side rib of Velmex Unislide Assemblies. They are not adjustable. (Pictured)

Internal Limits on  UniSlide MB90  

Internal Limits (MB90 Only - Standard) - The internal limits on the MB90 "J" Series consist of two switches, a control rod mounted along side the lead screw with two moveable brass collars and cover atop an additional 3" of dovetail base as shown. The collars are positioned on the control rod to activate the limits. The internal limits on the MA90 Series UniSlide Assembly are referenced by the letter "J" at the end. (Pictured)

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
