Velmex manufactures linear and rotary positioning stages for science and industry.
Established in 1967, Velmex makes UniSlide, BiSlide and XSlide Assemblies. They are useful for moving a probe, sensor, antenna, transducer or other objects. Applications include manufacturing and R & D. They offer a precise, modular design, in a very broad range of sizes and payload capacities at reasonable cost.
The UNISLIDE and BISLIDE assembly has the following advantages over ball and roller element positioners:
- Lighter weight with high strength aluminum alloys
- More compact than ball screw driven stages
- Resistant to impact loads
- Corrosion resistant
- Will operate without lubrication
- Some models can be supplied totally nonferrous
- Fewer parts
- Lower cost
Compared to steel or cast iron dovetail slides that have metal sliding on metal, the UNISLIDE and BISLIDE are lighter, and have much lower friction. UNISLIDEs and BISLIDEs have a thin layer of a Teflon compounded material bonded to the sliding element that minimizes friction and wear, especially when operating without lubricants.
