Anti-friction guidance mechanisms
expanded
The DualVee Motion Technology (DMT) range of anti-friction guidance mechanisms offered by HepcoMotion has been the subject of further development to extend its application potential.
DualVee Motion Technology (DMT) has been successfully employed in industrial linear guidance applications for over 30 years As an integral part of the HepcoMotion product programme, it has proved a popular choice for anti-friction guidance mechanisms, typically in pick-and-place units and packaging machinery that do not require the ultra-high precision offered by the HepcoMotion GV3 System

Anti-friction guidance mechanism options expanded
New track and wheel sizes have been introduced to an established high-speed anti-friction guidance mechanism, as have high temperature, vacuum and clean-room compatible wheels.
High load lifting units assembled to order
Winkel builds complete high load lifting units to meet customer's specific needs and Hepco is pleased to extend this service to UK companies.
Such is the popularity of this product that it has been the subject of further development to extend its application potential.
The various new options that have been introduced as a result of this initiative will benefit light duty applications in the clean rooms through to rugged transport systems working in hostile environments.
This linear guidance technology is now more flexible and even more cost-effective.

Locking device provides safe platform
The extensive menu of design elements within Hepco's GV3 linear slide programme allows specifiers to create the optimum linear motion system to suit both application and budget.
As before, the system is built-up from three basic components - tracks, guide wheels and bushings - all of which can be individually supplied to give the user maximum design flexibility and overall cost-effectiveness.
Several new wheel options have been introduced that save time and therefore cost.
New integral bushed wheels, for example, eliminate the need for inserting a separate bush into the wheel before assembly - this unique development reduces assembly time and component cost.
For low load, cost-sensitive applications the choice now includes new polymer over-moulded wheels; these are complemented by the option of crown polymer over-moulded rollers that can run on flat tracks.
The range also introduces new lower cost drilled track and Pristinox processed stainless steel hardened track for applications calling for enhanced corrosion resistance.
A further choice is the new MinVee, a low cost miniature linear guidance system using polymer or steel wheels and the smallest double edged track.
Wheel capacities across the entire range have been increased by up to 40 percent in many cases.
This has been achieved through improvements to the wheel's internal bearing design and higher manufacturing tolerances.
All this is available at no extra cost to the customer.
An extended range of wheel cover and lubricator assemblies for integral bushed wheels is also available to extend system life.
DMT is based on a double row angular contact bearing arrangement.
In common with HepcoMotion standard vee technology, DualVee uses opposing concentric and eccentric bushings that provide a simple but effective means of adjustment for free-play and clearance between the track and guide wheels.
The rolling contact between wheel and track provides a constant self-cleaning action.
Butt joining of the track is easily accomplished with DualVee enabling virtually any stroke length to be achieved.
The single edged tracks can be supplied in standard or custom lengths up to 6m if required, pre-drilled to suit individual design requirements.
By comparison with round or square rail recirculating ball guides, DualVee is 50 percent quieter and is also significantly cheaper to install, as no ground surfaces are required. Request a free brochure from HepcoMotion ...
