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.

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.

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.

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.

Velmex slides, stages and tables are available in manual or motor-driven configurations. Standard “off-the-shelf” sizes are built-to-order to the customer"s required configuration specifications. Custom sizes and configurations are also available. No minimum or maximum quantity requirements.

Cross Sections – The cross sections of the Velmex linear stages are a key differentiation. While the three Velmex linear stages all have bases with dovetail ways, they each have a different cross-section profile. (images above) The sliders (carriages) each ride on the ways differently.

Velmex UniSlide® Assemblies are available in a variety of configurations, models and sizes including Linear Slide Assemblies, Elevating Tables and XY Tables. All available as manually-operated or motor-driven stages. Linear UniSlides have a load capacity up to 400 lbs horizontally and 100 lbs vertically with travel distances to 42". UniSlide Elevating Tables and XY Tables can lift up to 100 lbs.

Velmex BiSlide® Assembly"s modular design makes it highly configurable for a multitude of different motion-control applications. A several models including free motion and lead-screw available both manually-operated and motor-driven. BiSlide Assemblies have a load capacity of 300 lbs. horizontally. BiSlide configurations come in travel lengths up to 80". The Belt-Drive BiSlide can travel 228".

Velmex offers several pre-configured specialized BiSlide systems including the Side Knob BiSlide, Parallel-coupled BiSlides and Belt-Driven BiSlides.

XSlide™ is a compact positioning stage for smaller loads and ideal for limited space applications, highly suitable for either high performance incrementing or scanning functions.

The Turntables, which can be spun freely by hand are ideal for mounting and rotation of test specimens, cameras, transducers, sensors, and mirrors. They are a convenient, accurate method of quickly positioning or rotating a payload. They use a heavy-duty spring-loaded tangent screw drive for fine adjustments.

They feature a 12° range of fine position adjustment accomplished by tightening the clamping knob which engages the tangent screw driven against a spring-loaded yoke. Velmex offers two series of Turntables – the larger A4007TS with a 4.13 inch diameter (10.5 cm) and the smaller A2505TS with a 3.15 inch diameter (8 cm). Both can handle horizontally-centered loads up to 200 lbs. (90.7 kg.)

Both the A2505TS and the A4007TS Turntables have many of the same features. The Turntables are only manually-operated and cannot be motorized. For motorized rotating tables check out our Rotary Tables.

Typical applications for Velmex Turntables include mounting and rotation of test specimens, cameras, transducers, sensors, mirrors and other components.

Velmex Turntables – Turntables can be spun freely into position by hand. Tightening the the clamping knob allows fine motion control. Turntables can be used horizontally. They are not recommended for vertical applications.

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.

Adapter Plates– A variety of adapter plates mount the Turntables to other Velmex products like UniSlides® and BiSlides®. For additional information see Turntable Adapters.

The A2505TS Turntable can be mounted to UniSlides using the A2500 adapter plates and mounts directly on UniSlides with a S2.5, S3 or S4 slider / carriage.

The A4007TSTurntable can be mounted to UniSlides using the A2400 or A4000 adapter plates and mounts directly on UniSlide stages with a S4, S6 or S8 slider / carriage.

In addition, since rotary motion is often performed for the purpose of processing, measurement, or some other subsequent operation, the use of rotary tables by themselves is rare.

Rotation mechanisms used in chairs and other equipment are also classified as rotary stages in the broad sense of the term, so they are used not only in manufacturing but also in home applications.

A crossed roller bearing is a bearing structure in which rollers are arranged between the inner and outer rings. The rollers are arranged in a straight row with a 45° contact angle, enabling the back bearing structure of a ball bearing to be realized with a single row, and the structure is capable of receiving loads from multiple directions simultaneously. The rotary table and cross roller bearings can be directly connected, which reduces the number of structural parts.

Since the rotational accuracy of the rotary table is directly related to the accuracy of the rollers, high rotational accuracy can be obtained depending on the accuracy grade of the rollers. In addition, since cross roller bearings have low frictional force and can be operated with light force, micrometer heads can be used in the fine-tuning rotation mechanism to obtain high positioning accuracy.
