Elevating Tables
There are four series of UniSlide Elevating Tables to address applications that require additional strength, rigidity and versatility. The models in three of the series are designed using the rugged proven UniSlide Linear Stages as the free-standing base mounted in the vertical position with a heavy-duty right-angle platform to carry the payload. The fourth series – the smaller A39 – pushes up from underneath the platform for a 360° unobstructed lift.
Velmex pre-configured Elevating Tables lift to a height of 15.5" (393.7 mm) with a travel distance of 9" (165.1 mm). The large table can handle a payload to 100 lbs. (45.5 kg.).
Velmex pre-configured Elevating Tables are manually operated. To lift a payload utilizing a motor, look at using a motorized UniSlide® or BiSlide® mounted vertically. Should the need for a different configuration, length or payload capacity arise, most manual or motorized Velmex linear stages can be mounted vertically and used as an elevating table.

Many questions can be answered by reviewing the "Features", "Model / Series", "Specifications", "Options / Accessories" and "Technical Documentation" sections for each product line. Additional FAQs about product comparisons, product construction, purchasing and shipping can be found on the company FAQ page.
Why would I use an Elevating Table?
You would use an elevating table when you require free standing vertical travel with a platform shelf. The Velmex Elevating Tables are more rigid then turning a linear stage into a vertical axis, making them more stable. However, if you do want longer travel distance or a narrower or wider frame, almost all Velmex linear stages can be converted to an elevating table with the addition of a base plate and a platform shelf. They can be engineered to provide added rigidity, support and stability.
What comprise Velmex Elevating Tables?
Velmex Elevating Tables are made of Velmex world renown UniSlide assemblies. They use a deeper base under the dovetail ways for added support and feature an oversize base for added stability in the vertical position. A right angle platform is mounted to the carriage that can be mounted in the inverse to add versatility to the travel envelope.
Do Velmex Elevating Tables use lead screws other than the "W1" with 0.100" per revolution?
Yes. Velmex Elevating Tables are standard with the W1 lead screw. Finer pitch lead screws with greater sensitivity are available as an option.
Do UniSlides need lubrication and how often?
Lubrication is important for motion systems or wherever you want maximum life and the lowest friction. UniSlide Assemblies can be lubricated with Velmex Lubriplate Aero®. Only a few drops are required to keep your slide running smoothly. The load and hours of use effect the amount and frequency of lubrication. See the user guide that came with your UniSlide for recommendations.
Can UniSlides Tables be mounted together?
Yes, UniSlides can be mounted together in XY, XZ, XYZ configurations. Mounting UniSlide assemblies in multi-axis systems requires the use of adapter plates and brackets. They also can be combined with Velmex Rotary Tables and our other linear stages to make custom systems to meet a wide range of applications. See UniSlide Options and Accessories for more information on the plates and adapters. Also see our examples pages for images featuring Elevating Tables combined with other Velmex products.
