BiSlide Motorized Linear Stages

Lead Screw with Limit Switches– A single-axis BiSlide assembly available in several lead screw pitches. The motor to lead screw connection is a precision-honed steel coupling that rigidly clamps to the motor shaft to maintain alignment without the need for key ways or set screw flats. Travel distances to 80 inches (203 cm).

Rapid Advance – The Rapid Advance BiSlide Assembly quickly positions the carriage by hand and fine-tune it with a one step jog using the motor. The Rapid-Advance feature disengages the drive screw so that the carriage can be repositioned. (Pictured is the manual version.)

Parallel-Coupled – Two or more identical single-axis BiSlides coupled together to handle larger loads and longer traverses. The operation of the BiSlides are kept in synch through a timing belt. Motor-driven, Parallel-Coupled BiSlide Assemblies can be either lead screw or belt-driven configurations. (Pictured is a system with 2 lead screw Parallel-Coupled BiSlides mounted XY. See the Parallel-Coupled detail page for more information.

Tandem – A combination of a motor-driven BiSlide and a Free Motion model with the same travel distance mechanically connected so that the carriages operate in tandem. The increased stiffness of this style BiSlide can carry larger loads.

Left-Right Screw Models (LR) – The slides simultaneously move toward or away from each other. Use for applications where two objects must share a common axis of movement..

Belt-Drive – This style BiSlide delivers longer travel distances, up to 19 ft. (228 inches/5.8 m) and faster speeds up to 3 meters per second. The high efficiency of the Belt-driven BiSlide make it ideal for moving light loads at high speeds and for continue duty applications. See the Belt-Driven detail page for more information.

Please note: While we offer 10" and 20" Belt-driven BiSlides for special applications, travel lengths under 30" are not recommended for practical use for high speed or continuous duty applications.

Petrographic Analysis Positioning Systems – Used for measuring air entrainment in concrete. Can be a UniSlide or BiSlide® System. For more details on Velmex systems for Petrographic Analysis, please visit the Velmex Petrographic System page.

Deflection: a = 0.000011 degrees / in-lb (F x d = in-lbs)

The part number can be found on the side of the BiSlide Assembly.

BiSlide Framing - The versatility of the BiSlide's modular design enables building of complex configurations. A variety of framing components can be combined and connected, disassembled and reassembled in alternate configurations to build BiSlide structures as needed. For more specifics and to see the framing components, including plates and brackets, in use on a BiSlide stage visit the BiSlide Adapters page.

T-Slot Plate – rugged, hard anodized aluminum extrusions with abundant T-slots for multiple attachment possibilities. The T-Slot Plate creates a heavy-duty support structure for building BiSlide mounting and framing structures or configuring multiple coordinates.

I-Beam BiSlide Base –The extruded I-beam base is made from a hard alloy aluminum and includes T-slots on each side to easily connect BiSlides to each other or attach the BiSlide to a frame or base structure.

T-Nuts , mounting bolts and other hardware – to create strong, secure attachments. Can also be used with the cleats.

Cleats - use BiSlide cleats to create rigid XY attachments, mountings for optical tables and attachments to other T-slot framing systems. The cleats are also used to secure BiSlides for longer travel distances and to support larger loads. Cleating Recommendations.

MC-1 – Standard 1 hole cleat. Mounts the BiSlide to a frame / base / surface. Can be used to mount to other BiSlides in an XY, XZ or XYZ configuration.
MC-2 – Standard 2 hole cleat. Mounts the BiSlide to a frame / base / surface. Can be used to mount to other BiSlides in an XY, XZ or XYZ configuration.
MC-3 – 2 hole cleat with 2" center to center for use with optical benches with 1" or 25 mm centers.

Adapter Plates and Spacers – use BiSlide adapter plates for vertical mounts; to create a larger base support; to mount Velmex rotary tables and turntables to the BiSlide; to as auxiliary payload mounting plates to support larger payload footprints. For more specifics and to see the framing components, including plates and brackets, in use on a Velmex stage visit the BiSlide Adapters page.

MSPP-1 Foot Plate – Used as part of the foot for BiSlide bases and post assemblies.
MSPP-2 Adapter Plate – Multipurpose adapter plate (4.6" x 4.6" x 0.375")
MSPP-3 Adapter Plate – Used to mount Rotary Table (A48 or B48 Series) to BiSlide
MSPP-4 Adapter Plate – Used to mount Rotary Table (A59 or B59 Series) to BiSlide.
MSPP-5 Adapter Plate – Use end mount BiSlide extrusion.
IM001-130-131 – Payload plate to expand the carriage (8" x 8" x 0.375")
IM001-130-132 – Payload plate to expand the carriage (12" x 12" x 0.375")
XS001-20 – connects an XSlide to a BiSlide.

Foot – Acts as an adjustable foot for BiSlide bases and post assemblies. (LFS-1) (Shown with a MSPP-1 foot plate.)

Angle Brackets and Gussets – Use XZ angle brackets and gussets as braces for vertical BiSlide assemblies perpendicular to the X or Y plane to provide higher rigidity. They are available in various sizes for vertical and gantry mounting.

For more specifics and to see the framing components, including plates and brackets, in use on a Velmex stage visit the BiSlide Adapters page.

Post Assemblies –Attach at right angles to the BiSlide Assembly to provide a convenient method to connect rotary tables or other accessories at a right angle, a distance from the carriage surface. Supports an adapter plate either vertically or horizontally.

Preconfigured Frames/Bases – See BiSlide Adapters for more information.

F2 Style has I-Beam top rails running parallel on two sides. These are ideal for supporting parallel coupled BiSlide Assemblies.
F4 Style bases have I-Beam top rails on all four sides for maximum support of heavy loads.

Velmex will design and build custom bases and frames as required to meet application and customer requirements.

Additional Carriages - Additional carriages (sliders) can be added to all models of BiSlides to increase the carrying capacity of the slide.

Left-Right screw motion - 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.

Note: Maximum carriage separation = distance of travel - (4.6" x 2).
Travel of each carriage = separation / 2

Outboard Adjustable Limit Switches– Mounted in a track on the side rib of Velmex BiSlide Assemblies to prevent over-travel. An optional third limit switch can be added between the two standard limits and used as an adjustable home switch. See Limits for more information.

Way Covers (-WC) – Protect the slider and dovetail base from dust, dirt and grit that could hamper the efficient operation of the slide. They also extend the slide's life. Way covers increase slider height and reduce the travel length of linear BiSlide stages.

Way Covers can only be used in horizontal applications and at a maximum travel of distance of 10 inches. For more details see Way Covers page.

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 BiSlide assemblies. An encoder, mounted directly to the slider gives a true and accurate reading eliminating lead screw and backlash errors.

The VRO is compatible with all 5V incremental encoders. It can monitor one or two axis. Fully functional, it features automatic memory back-up of settings, sleep mode and self diagnostics. It's highly visible, wide-screen LED display makes it easy to view the positioning results. SEE: Velmex Controls on the Encoders and the VRO Readout for additional details.

Motorized / Manual Operation - All BiSlides are designed to accommodate NEMA size 23 and size 34 motors without modifications. They are the easiest to convert from manual operation to motorized. Simply remove the knob and mount the motor. Then add limit switches. (Conversion kit pcitured - Motor sold separately.)

Motorized / Manual Operation– It 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.

Motors - BiSlides are compatible with Nema DC step motors – 23 or 34. Other motors including gear motors, servo motors and high resolution step motors in both AC and DC can run Velmex BiSlides. Motor-driven BiSlide Assemblies are motor-ready.

The motor is purchased separately. Customers can mount their own motors, if they chose. SEE: Velmex Controls on the Motors for additional details.

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. Gear motors, servo motors and high resolution step motors in both AC and DC can run Velmex UniSlides. SEE: Velmex Controls on the VXM Controller for additional details.
